A bottleneck inquiry: AMD with high end GTX 5xx cards

post #1 of 19
Thread Starter 
So,

I'm leaning towards upgrading my GPU now instead rather than a platform change to Sandy Bridge.

Will the following processors be a bottleneck to the 570 or 590 in such a way that the Sandy Bridge upgrade + my 460 oc'd would be more sufficient of a solution?

1) B55 at 3.2ghz
2) 965 BE @ 4ghz
3) 1090t @ 4ghz

I'm not waiting for Bulldozer either. I just want what will be more of a better bang for buck upgrade.

Nope. Not on this board at least. Even the slightest OC will BSOD.

Get a 955 for $115 and call it a day.

Okay can you overclock your dual core processor or what if its a tri core?
A tri core x3 at 3.8 3.9 should be okay in most games.

Haven't tried tri-core. But I don't want to sacrifice cores for an OC. I play games that support quad cores also do video rendering, so cores are important for me.

alright then havew you tried lowering your ht link to 1600mhz and seeing if that helps?

I know some people who have unlocked quads that wont boot with the htlink above 1800 so maybe try that.
ALso are youi overclocking with multi or fsb?
You should try the 3 core thing so then you know its a core holding you back.

Any amd cpu will bottleneck anything more than a single 580. Using 590's, 6990's, SLI 570s/580s/6970s/6950s/480s/ect is a waste

Single cards are fine (not the 590/6990).

I saw my fps jump by huge amounts moving from a 4.2 955 (very strong oc for amd) to a 4.7 SB (weak/average oc) with my 570sli, and many many others have seen the same thing. My GPU's were getting usage numbers way lower than average and I was completely capped by my cpu/platform.

Edit: Thats assuming gaming at 1080p. Also, it would perform better than the alternative 460/sb setup you listed, so I guess the order you upgrade it doesn't matter, so long as you don't buy more gpu now than your cpu/plat can handle.

True, but he's asking for single 580, no? At least that's what I understood..
PhenomII quad @4Ghz won't bottleneck a single 580
