The answer depends on what you want to do. If you are an extreme gamer than there’s nothing quite like an i7 920 with an XFX X58i Mobo. However,if you don’t want state-of-the-art and can live life with less than photo-realism, than try the XFX 7501 or nForce 760S mother-boards.
For Ram, try 6GB (if your mother-board supports it) with the corsair DDR3 Ram. However, even 2GB is enough if you’re not into extreme gaming. I think anything over Core i7 920 is over-kill. It’s highly unlikely you’ll be using even the full power of the 920,much less the extreme edition. However,if you look around,I’m sure you’ll find i7 extreme. Intel did launch the 940 in Pakistan and probably has launched the EE version too.
