Need advice on $1700 gaming rig.

The GTX 590 has issues, get a GTX 570. Get a bigger case anyway.

Would the Coolermaster 922 case be large enough or should I go up to the 932? And would a single 570 be good enough for the games I will be playing (Starcraft 2, Shogun 2, Crysis 2, fallout NV). If not, would going SLI with two 570's be a good idea?

The 922 is large enough. A single 570 should be good for any game on max settings except for Crysis and mostly Metro 2033. If you plan more than one monitor get a HD 6970.

For SLI in the future get a 850W PSU - XFX, Corsair, Seasonic, Antec.

After deciding on SLI and making a few changes (for many reasons) this is what I've got, let me know if this is any good or even if it works.

I'm lucky to be able to raise the price this much, I got more money than I thought I would off a old computer. So let me know if there is anything I should change, or remove.

What kind of speakers do you have? A lot of people find that the onboard sound on the mobo is more than enough, especially for gaming. My speakers aren't very fancy so I saved money by not buying a sound card.

If you're looking for speed, then you definitely need to get an SSD. You will be amazed at how much faster everything loads. I'm waiting for the OCZ Vertex 3 to be back in stock so I can get one.

This may be a dumb question, would a SSD replace a standard hard drive or would I have to get a SSD with my hard drive?

Load your OS and the main games & programs onto the SSD. Movies, music & pictures should be stored on a secondary HDD. A 128 GB SSD would be sufficient for most people and I use a Samsung 1 TB HDD for storage. The time frame from when you push the power button up until the Windows screen comes up will be 30 seconds or less. I have an older SSD on my laptop and I don't like to use my i5 2500K gaming computer b/c it doesn't have an SSD yet.

I have a WD SiliconEdge Blue SSD, which I believe is either late 1st gen or early 2nd gen, and it boots in maybe 45 seconds max. I'd recommend at LEAST 64GB; I have W7 64 and Office 2010, along with all my drivers and such and still have ~10GB free space. My older 500GB HDD provides storage for all of my games and programs.

I not an expert in regards to building a computer, but this is what I put together for my gaming rig:

i5 2500K
MSI P67A-GD65 mobo
8 GB Kingston memory
MSI Geforce GTX 570
Corsair H70 cooler
Antec 850W PSU
Samsung 1 TB HDD

I plan to get the OCZ Vertex 3 SSD once it's available and another Geforce 570 for SLI to play Battlefield 3 when it's released later this year. I figured this computer should last me about 3-4 years or so before I would need to upgrade again.

Good luck with your build.

Thanks for all of your help, I'm going to order my parts now.
