Hey I was wondering if my 6 year old Intel Pentium D 925 with 946PL/GZ chipset will be compatible with a Radeon HD 7850
I currently have a GT 9600 and a new system is out of the question. I use it to play BF3 Skyrim and ME3 and it can just barley handle them on single player at the lowest settings. it only has PCI-e 1.0 so I'm just wondering if it would be compatible no need to say I'm overkilling it this is just a question of compatibility.
Compatible yes, but you will not see anything close to the 7850's full potential with such an antiquated CPU at the "helm" so to speak. I would strongly advise against it. Skyrim and BF3 are both CPU heavy games, most likely that old ass Pentium D (which honestly, was junk the day it was made) is holding performance back more than the GT 9600.
That pentium is bottlenecking your current GPU, you have better luck upgrading the CPU rather than GPU, like what nekulturny and spentshells said, spend the money on upgrading your CPU, check your motherboard compatibility chart.
