New Radeon 5870 Underperforming :/

Okay I just installed my new ATI Radeon HD 5870 which left my wallet feeling a lot lighter.
Overall I'm very satisfied with it but I'm a little concerned the rest of my computer is bottlenecking it.
I only get about 100fps max in TF2 and it regularly dips down to 60fps.

Is that to be expected with the following specs / what's the most valuable upgrade I can make to get more out of the card.

PCI Express 1.1 (x16)
Intel Q6600 (2.4ghz) Stock cooling
26" Screen w/ 1920x1200 res
6gb (2x2 + 2x1) DDR2 333.3MHz ram

I upgraded to a 650watt power supply which is plenty.
I don't have any other cards installed, and the only other things drawing power are the optical drive, mobo, and hard drive.

Tell me if you need any more info, thanks.

  1. You need to OC your Q6600 to 3 GHZ and above.

    Agreed, even a overclock to 3.5Ghz may not fully unleash your card, but get it as close to that as possible, and DEFINATELY somewhere near 3.0

    Did I read well ?
    6gb (2x2 + 2x1) DDR2 333.3MHz ram

    get some faster memory and overclock your cpu :)
  4. Yes that is the correct number for the ram frequency. I thought that might be the major issue. Does everyone agree?

    p.s. I accidentally posted twice, is there a way to delete my other post?
  5. 1+ to abswindows 7 alittle overclock would help quite a bit, but your ram my be putt a pretty significant bottleneck on your system. 333mhz is pretty slow in todays standards i would try to shoot for at least 800mhz ddr2 get a 2x2gB ddr 2 which i just looked on newegg and the cheapest set was 77 dollars. but if you boards supports ddr 3 then you might want to go with ddr 3 because the cheapest 2x2gB kit is the same price and 1066

    Get some ddr2 800 mhz or 1066mhz and try to get an after market heatsink ( pay under 50$) and you should get a 3.3ghz q6600 that should handle fine enough your beast :)
