Hey guys I m planning on buying a new graphics card My system configuration is:- core2duo E4500 @ 2.20GHz processor ASUS P5GC-MX motherboard 1GB Kingston RAM 160 GB Seagate HDD 19" Viewsonic monitor I have shortlisted Zotac GeForce 9400GT card. I would mostly be using it for playing racing games mostly NFS series as I m a big fan. I m also going to upgrade to windows 7 when they will be released. What u guys think? Does installing graphics card improve the performance of my CPU? Also I want to upgrade to 2GB RAM? Is it a good decision? My budget is Rs 5000.
