as ur budget is 40k, corei7 is out of question. The P55 mobo have been delayed to September, so if u really want corei7, w8 till sept-oct.
In fact this is a bad time to get a new rig/upgrade. W8 another month.
bcos of this :
techPowerUp! News :: Intel January Price Cuts Update
and the possible arrival of phenom 2 in india.
In march ATI will be releasing RV770 refresh. They are 40nm dies(frm 55nm) and have more shaders. RV740 will have 640sp. RV790 is
expected to have 960 Sp. They will be called HD4950,HD4970, etc. These cards are gonna be cheaper, faster, cooler and more energy efficient.
So save ur cash for now and spend it after 2 months.
