Video card variance by computer

(1/1)

TouchuvGrey:
i have 4 desktop computers here in my house.
They range from Homebuilt with an Asus MB, and 12
gigs of RAM to a $399.00 Walmart special.

   If i were to put the same video card in each ( presuming an
adequate power supply ) would there be much if any variance
in their performance ?

Mike:
If the CPU is fast enough to feed the card it should be similar.

Claggy:
Depends on what GPU and what app you're measuring the performance with,

If it's with an app like the x41xc Cuda app which has a minimal CPU time requirement then there shouldn't be much difference,

If it's an app with a big CPU portion like Hybrid Astropulse or Einsteins BRP4 GPU app then CPU and MB speeds will make a big difference,
