Additional Comments:
Hi, this is my first post. Was looking for some advice on a new system. I have some idea of what I want, but I have a couple of questions:
Will my PSU be able to handle two 460 1GB GTXs with an i5 2500k overclocked?
How important is RAM in overclocking and bottlenecking in general? Can I get away with mediocre ram without seeing a huge drop in performance?
Right now, these are the parts I have in mind:
COOLER MASTER HAF 932
ASUS P8Z68-V
INTEL Core™ i5-2500K
COOLER MASTER Hyper 212
CORSAIR 8GB (2 x 4GB) Vengeance™ LP PC3-12800 DDR3 1600MHz CL9 (9-9-9-24)
OCZ 120GB Vertex Plus SSD
Tell me where I can improve/save money.

Ram won't be a bottleneck as long as it isn't DDR2 or something like that.

That Toughpower will easily handle 2 GTX460.

I would get an Asrock Extreme3 Gen3. It is cheaper and still has the same quality with yours.

You might want to get a Cooler Master Hyper 212 EVO. It is an improved version of the 212+

Everything is pretty good. No problems.

Thanks for the help. Would I be better off buying all the parts separately or buying from a custom build site? I had avadirect in mind, but I don't want to be overcharged. Will I be losing a lot by ordering a custom system instead of buying the pieces separately?

If March is your target - chill a keep your eyes open - things change so fast in "computerland". When you get a couple weeks away from pulling the trigger - finalize.

I see. One more question. I had an issue with my previous system where I would get temps a tad bit high for my liking, despite having a good cooling system(TEC). I'm thinking it was because of my case having only two fans, one intake and one output. Also, it was a mid tower, and I had a bit of a problem installing RAM and GPUs. Would getting a mid tower with more fans alleviate my heat problem? Or should I be looking for a full size case? Can anyone recommend a spacious, affordable mid tower case?

Had another concern about my gpu(s). I initially planned on reusing my 460GTX and upgrade to sli sooner or later. Would I be better off price/performance-wise getting a higher end GPU?

Might be making my purchase sooner. Didn't get any responses about the GPU, but I have a different concern. I've decided to keep my previous computer intact, so that means buying a new PSU. I've had this one in mind, because my previous one was rather reliable(thermaltake toughpower 750w).

I don't know about rails, will this PSU be able to support the system below or should I consider a different one?
