Upgraded video card and now

upgraded video card yesterday to a Asus gtx560 ti 900mhz installed latest driver from nvidia and now windows 7 loads very slow about 10min hangs on welcome screen for long time games are very choppy seem to have a very high cpu usage for some reason thought maybe it was psu but its a thermaltake 750w should be powerful enough shouldnt it. nothing seems to be working correctly

cpu intel Q6700
mb asus p5e-vm hdmi
memory 2gb

the old video card was an ati 3870 and i did unistall the old drivers for this

    any thoughts anyone
  3. Your PSU isn't the problem.

    Your system RAM is definitly going to cause a problem.When the system doesn't have enough RAM it will use the HDD as if it were RAM which can result in really slow performance.But my guess is that your previous GPU bottlenecked your CPU, not having it work as hard, and now with a GTX560ti it's allowing it to work harder but now the CPU is the bottleneck.
  4. Definately add more ram and also overclock your cpu , you are getting a bottle neck, you got yourself a great card you just need more grunt to push it.
  5. ok the mb i believe is rated for 8gb memory but i am running 32bit windows 7 do i have to upgraded windows to 64bit in order to increase ram to 8gb or will the 32bit windows read it
  6. Yes you will have to upgrade to 64 bit
  7. Thanks I will give that a go and let you know how it works out
  8. Ok goodluck, increasing the ram to 8 gig and running 64bit will help quite a bit.
  9. I'm guessing that you previously has a 512MB 3870 (I don't think there were any 1GB). The slow startup could be remnants from the old drivers so I suggest uninstalling your current drivers, use driver sweeper to remove any traces of AMD or NVIDIA drivers, and re-install the drivers. If you're using the same settings as you were when you had your 3870 and experience worse performance then it might be the drivers. Of course if you raised settings first then it could be lack of RAM :p. You can increase your RAM to 4GB, but since you have a 32-bit OS you will only be able to use a little under 3GB.

    I think it's a little expensive to get 8GB of DDR2 at the moment as you'd have to go 4x2GB. You would also have to upgrade your OS to use it. I say just get either a 2GB or 1GB kit (2x512MB) to last you till you move to DDR3 and 64-bit
