Finally she is done. Can't believe the difference it makes in iRacing. Only have $450 in it. Not only does the graphics look better but it is so much smoother and faster. iRacing just got a lot more fun. I bought a used Sapphire HD 6950 2GB and a new old stock ASUS gaming motherboard. The rest is new. I went with a lower end CPU for now (Pentium G2030 3.0 GHz) and it exceeded my expectations for iRacing. Eventually I will upgrade to a i5 quad-core but this pentium does the job plus some.
