PII X4 945 a bottleneck for GTX580?

[MR STROKE]

About to pull the trigger on upgrading my 5870 to a GTX580. Will a PII X4 945 suffice? or not worth the upgrade with out an entirely new CPU?


current specs-
PII x4 945
8g
5870
Dell 30" 2560x1600


thanks

No, not at that resolution. Can you give you cpu a little overclock?

Edit: at that resolution, I'd might go for a 6970 and a good overclock for less money.

at that res its pretty much a non issue with a single 580. just oc the cpu that you have since a noticeably better cpu would require getting a new mobo.

Agreed with the two above. At that res your fine

6950 instead ^-^

Think you ll be cpu bottlenecked, which makes going for a much more expensive GPU give little to no extra performance, at a very high price cost. In short go for something cheaper, you ll be happier about the saved $.

*or*

get a 2nd 5870 (what are they now? 199$?)
OCed 580 is faster than 2x5870 but not by much....


here is why: (AMD Phenom II X6 1090T BE @ 4,2GHz)

From techpowerup:

a 580 is a faster card... but going from 33.3 fps --> 38.5 fps (isnt that impressive).
2 x 5870s give a 1x 580 a run for its money thats for sure..... So another 5870 to crossfire with your first might not be a bad idea.

Did you look at the resolution? I wouldn't get 1GB cards at that res. The extra RAM on the 580 should make a noticeable difference.

If you have the 1 gb version, the bottleneck might actually lie with the card at that resolution.
