CPU bottleneck

post #1 of 3
Thread Starter 
Greetings folks. So, i'm looking to upgrade my computer some before i go off to University in september. Since i'm going to be going into Computer Science, i decided that i should probably update my computer some.

I was looking at getting a new AM3+ motherboard and waiting for the Bulldozer processors to come out before upgrading my already dated processor. However, i was wondering by just how much my current processor (if OC'd to 3.6ghz, unlocked) will bottleneck a 6870/6950 (haven't decided which to get yet). Will it be significantly noticeable in video games?

Edit: On a rather unrelated note, and in the quite wrong section i suppose, but would it be advisable to upgrade my power supply as well before getting a new card? I know my PSU isn't exactly very good, but i was hoping to hold off on upgrading it when i get my new processor.

First off you will not need a new PSU for a single 6950 or 6870. That 700W is fine.

Now as far as the bottleneck goes, in the vast majority (80%+) of video games you're going to be fine. Now when it comes to certain games like SC2 and F1 2010, you will see a bottleneck. So basically I don't think it's worth upgrading. Especially considering you don't know what Bulldozer performance is going to be like. If you really want to upgrade, I would go the 2500k route. It's a really great value for the money. From what I've seen on the B0 stepping Bulldozer leaks, it doesn't look good at all (but keep in mind this is not a final revision, B2 stepping should be improved). If Bulldozer comes out and beats Sandy Bridge (which I doubt it) and you were to buy a 2500k now, it's still going to be a great chip no matter what and will not bottleneck any games at all for a while.

I currently do not see much Bottleneck with my 925 x4 @ stock 2.8Ghz with my 6950 on Red Faction Armegeddon, but soon I will get my copy of Metro 2033 on Ebay to give my CPU/GPU a true stress test and I will let you know how my FRAPS performance is with that game on Highest and x2MSAA and 8xFiltering
