Hi Carlos,

A single GeForce GTX 670 will consume, at a maximum, 170W of power. So two of them will consume 340W of power, according to NVIDIA's detailed specifications on the GTX 670 itself.

As for power supplies, you would probably want to get a 650-850W PSU to cover yourself. I would specifically recommend the Corsair AX760. This is one of the best power supplies in its class, and will handle the two GPU's running in SLI without a problem whatsoever.

Hi Jeremy,

When looking at any high-end kit of memory, they're each going to be great. Choosing Corsair, G.SKILL, Geil or any other brand will give you some kick-ass memory that you won't regret purchasing.

I think it'll come down to two kits, G.SKILL's TridentX memory, or Corsair's Dominator kit. You can get the G.SKILL TridentX 32GB kit at 2400MHz, which I think is the best option, especially if you want it to have some overclocking headroom.

Alternatively, you can look at something like Corsair's Dominator kit, which comes in 1600MHz.

G.SKILL's TridentX memory is probably the way to go, and you can score this from Newegg's website for $309.99.

Hi Grant,

Definitely. The 500W power supply you have will be more than enough for the Gigabyte Radeon HD 7950 GPU, even if it were the OC model, or any other HD 7950 for that matter.

The Gigabyte HD 7950 requires two 6-pin PCIe power connections, which the Strike-X 500W has. The HD 7950 is a very efficient GPU, and a system under load would only pull around 400W with this GPU cranking along inside of it.

The Aerocool Strike-X 500W will be fine, so have fun with your new upgrade!

Hi Rashid,

Both of the monitors that you're torn between are going to be great. Both monitors are pretty much on par with each other apart from a few things, something you already know. The Samsung has a refresh rate of up to 120Hz, and the ASUS, with 144Hz.

For everything I've read on the ASUS, the 144Hz isn't really noticeably better than 120Hz - so if you were going to use this as the selling point, you might want to hold on. Even if 144Hz was something that was noticeable, you would require the frame rate to notice it - thus, you'd need to be pushing 144 frames per second in order to justify the 144Hz monitor.

I don't think you'll see this, and I don't recommend the ASUS over the Samsung.

Samsung's S27A950D - which is the monitor I'm looking at while I reply to your question - is an excellent monitor. One of the more standout features over ASUS' VG278HE, is that the S27A950D has DisplayPort. Your video card has a DP connector, so this is something that is useful to you.

Sure, there's no difference to you whether you use dual-link DVI or DisplayPort, but it's there, just in case. You might want to upgrade and buy a second, or third 120Hz-capable monitor, and you'll need DisplayPort for that.

As for your breakdown in questions:

1.) If you are after picture and color quality, you might want to look at IPS-based panels, Samsung make a few and so do Dell.

2.) You'll need to use the dual-link DVI connector, or if you go for the S27A950D, you could use DisplayPort.

3.) This depends on the content you're playing - movies and TV are filmed and played back at 24 FPS, but games - if you're able to reach 120 FPS - will look absolutely amazing (in terms of fluidity) compared to 60Hz.

4.) I wouldn't bother with 3D gaming if you're not going to jump right into it. In my opinion, NVIDIA's 3D Vision is a superior technology because of the active shutter glasses - but this would require you to buy a 3D Vision-capable monitor, as well as a new NVIDIA GPU.

Hi Tony,

The video card you've already got would do a good job keeping up with the HD 7790, so upgrading to the new card won't do much for performance. You could go two ways here - upgrade to the HD 7790, and sell your card - trying to secure as much money as you can to put toward another HD 7790 and CrossFire those GPUs together.

Alternatively, hunt the Internet for a second GPU identical to yours and CrossFire it with your current card. You've asked where to find one, so I'd suggest the Overclockers Australia forums. They have a Shop & Swap section, where you could either sell your GPU - or put up a Wanted to Buy ad for another GPU identical to yours.

If that fails, then reconsider your options again and maybe sell your card to raise some funds, and spend the $50-$100 you'd get for your GPU and put it toward a HD 7870 or HD 7950.

Hi Ahmad,

If you were thinking of upgrading to the Radeon HD 7850, that's a great move - it's a great GPU for the price. Have you also looked at the Radeon HD 7770? You might want to take a look before you dive in. Not only the HD 7770, but the GeForce GTX 650 Ti Boost, too.

As for the CPU bottleneck, your Core i3 processor should be fine. You've got 8GB of RAM sitting there, too. I would say that your current Cooler Master 500W PSU is enough, as these mid-range GPUs do not consume that much power. I think you'll be fine, don't worry about upgrading your PSU just yet.

Of course, an i5 or i7 processor would help - but you should be okay for now. I would pencil in a CPU upgrade for the future, though.

Hi Daksh,

You could not have asked a better question, as I have pretty much the identical setup right here, on the PC I'm replying to your question on. I run the same Samsung S27A950D monitor, and maintaining 120 FPS in the latest games is hard on any system.

A single Radeon HD 7970 will be ok, but you won't be pushing 120 FPS in games like Battlefield 3 or Crysis 3. I would definitely, without a doubt, recommend the CrossFire HD 7950 solution. I take it your motherboard is CrossFire compatible, and your power supply has enough juice to run the two GPUs.

You won't be sorry with that setup, and you should push very close, if not over 120 FPS in most games. Crysis 3 is hard on systems, but if you scale the graphics down a little (no anti-aliasing, etc) then you should be fine. Enjoy!

Hi Riyaad,

I'm a huge fan of Corsair SSDs, running a bunch of them across multiple machines. They are damn fast drives, and they don't cost an arm and a leg also. Backed up by this we have some impressive drives from Samsung and OCZ, too.

Newegg sell these awesome SSDs at the 240GB size for $219.99. This is not bad considering you get up to 550MB/sec reads and up to 470MB/sec writes. They are simply amazing value for money.

Alternatively, you can take a look OCZ's Vector 4 in 256GB, which sells for $269.99. This has read speeds of up to 550MB/sec and write speeds of up to 530MB/sec. It's a little under 20% more, but this gives you some options between some of the top SSDs on the market right now.

Hi Duarte,

For your system to be capable of running games maxed out at 1080p and at a minimum of 45fps, you shouldn't need to do too much. I would suggest one very fast GPU instead of SLI for 1080p, so maybe you could go towards a GeForce GTX Titan, or an AMD Radeon HD 7970 GPU.

Either of these would max out every game out on the market at 1080p @ 45fps, without an issue. SLI and CrossFire would push out your power consumption (something like ~600-650W+ is what I'd recommend) and then your motherboard would need to be SLI- or CrossFire-capable.

I'd suggest the GTX Titan, or HD 7970, which will set you back just as much as a pair of HD 7970s.
