Q9300+HD5970 BOTTLENECK

Hello guys, i recently ordered a hd5970, but i am now worried about how much my cpu will hold it back. Should i cancel the order and get a hd5870 to reduce bottleneck?. My cpu is a Intel Core 2 Quad Q9300@ 2.5ghz which has been overclocked too 3.8ghz and has had no problems with my current HD4870x2 setup. Should i upgrade to i5/i7 build or will the quad do its job for now?. Thanks guys.

My system:

Intel Core 2 Quad Q9300 @3.8ghz
4GB Ram @1066mhz
HD4870X2 2gb
MSI P45 PLATINUM
500GB seagate barracuda + 300GB Western Digital

  1. At 3.8ghz it will be more then plenty to drive the 5970. What res you gonna be playing on?
  2. Thanks for the reply, 1920x1080.
  3. You will be fine IMO a single 5870 will not give you much of a gain in performance over the 4870 x2.
  4. I would cancel the order, if you're not getting the FPS you want with dual 4870s (~5870) OC them, if its still not enough its probably time for a new build.
  5. Its just that the hd4870x2's take up a lot of space and there old. And i kinda wanna run gta iv smoother then the hd4870x2's.
  6. GTA IV is very CPU intensive and a 4870X2 is more than enough for that game.

    You'll need a faster CPU if you want performance there.

    Bench below is using a 3.5ghz i7.



    You'll want more CPU power with a 5970 on 1080p. Not that you won't see an increase, but there will be some bottlenecking on most games.
