bottleneck for my 9800gx2??

post #1 of 11
Thread Starter 
i recently got the 9800gx2 instead of the 8800gts 640mb and a new psu (thermaltake toughpower 850W). im aware without a 7 series mobo for a start, im bottlenecking the GPU due to not having the pci-e 2.0 slot. i would like to know by how much so i know if its worth upgrading the mobo. also, is the cpu or memory currently installed possibly affecting the 9800gx2?

specs:

AMD ATHLON 64 X2 6000+
2GB GSKILL PC2-6400
Fatal1ty AN9 32X


thanks in advance

You are NOT bottlenecking the card from PCIE 2.0 bandwidth, we can't even fill PCI-E x16 yet, 2.0 is just gravy so don't worry about that.


The only thing that is bottlenecking your card is your CPU, it could use a good overclocking. That will help, of course ANY CPU will bottleneck that card.

In my opinion it might me your mobo. the pcie-e 2.0 might give you more bandwidth (correct me if im wrong)

Trust me, you're wrong.


Ask half the 8800GT owners here.

so its not that bad if i dont have the pci-e 2.0 slot, well thats good news. but i really cant overclock my cpu and acually i dropped it to 3.15ghz. does that mean im better of getting an intel quad cpu and 7 series mobo or shall i just leave things as it is?

If you game at 1900*1200 then you are not getting bottleneck but the CPU at all.

well for the moment, im using 1280x1024 resolutions for gaming. i was just wondering as i dont want open another topic, i got the thermaltake toughpower 850W, could that possibly take on 2 cards of 9800gx2 (quad sli)?? i currently just have one 9800gx2
post #9 of 11
Max power draw for one GX2 is 192W so 2x is around 400W. Those power is from 12v rails. Based on what you have, a good 750W PSU should be fine so yes, that 850W is good enough for 2x GX2.
