  1. According to the graph from, I'll only need at least 415W for the GTX 670. Is that true provided that most builds I'm seeing use 600W or 700W?

  3. Could you explain the reasoning behind why you chose that PS?
  4. 750w is more than enough for CFx cards and you can overclock with plenty of headroom. With it being from Corsair you really cannot go wrong, they are the creators of great PSUs.
  5. Hi vitaramen, are you planning on gaming on more the one monitor?
  6. On one monitor for now. Maybe 2 in the next year or so.
  7. If you plan on using two monitors 1 7970 per monitor would be amazing... for now 1 would suffice...
  8. Well, what i was trying to figure out is why bob would recommend xfire 7970's for the average gamer One 7970 is going to be able to play everything off one monitor at max settings. So to me in my opinion that second 7970 is wasted money. The price to performance ratio for another 7970 just is not there.
    However, the core components he chose are pretty good. I would just take out one of those 7970's and buy a Decent Solid state disc. For that kind of money you should definitely be putting one in your system. Then since you are running just one 7970, you would not need 750 watts. Get something like the XFX 550. you will be all set for quite some time.
  9. According to a thread on here somewhere (can't find it), the performance between the 7970 and gtx 670 is relatively the same with the 670 being a little cheaper. Thoughts?

    In addition, regarding the PS. I read that you're not supposed to skimp out on them, so could someone please tell me the difference between the one recommended
    Corsair Builder 750W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply

    and this more expensive one
  10. They do perform relatively close. Either would be a good graphics card for a gaming computer. But my personal preference tends to lean towards the 7970. If you are just going with one graphics card. You do not need to spend that much on a power supply.
  11. 7970 performs 10% better at a 10% high price, I would go with the 7970 only because you can fit it in your budget and it will last you longer with ease.

    The difference between the two PSUs is negligible unless you have VERY expensive electricity were you live.
  12. Hmm ok last question. That optical drive along with the popular

    seems to be giving people problems with Windows 7. I plan on installing Win 7 so any concerns?
  13. It's windows 7 ultimate that is the problem not windows 7 64 bit normal... there should be no problem
  14. Thanks for both of your help. I am ordering the parts now :D
