i used c2q as a short for of core2quad cpus
your pciex1 are v1 (pciex8 v1 = x4 v2 = x2 v3 in bandwidth)
yes yours is v1 (provides 250mbyte/s bandwidth)
using a dedicated phyx card for non phyx games will not gain any performance
OK. So basically the Only performance gain I would get from adding this card would be Physics related. I get it. I think I will just scratch this idea and get the 560 ti. lol
Thank you to everyone who replied. I appreciate your help!
