Upgrade old pc

You will net only a very small performance boost adding the extra RAM.

May I suggest that, with LGA775 at it's End-Of-Life cycle. your funds would be well-spent saving toward a LGA1155 board (the DDR3 RAM alone cost's nearly half) where even the bottom tier i3-2100 will outperform what you currently have - but would cost you the same as a better CPU.

I think thats right, building a 1155 pc with some ddr3 would be better than upgrading this one, but before doing it, I wouldnt like to leave this one on the dumps as it can run quite a lot of games and I would like to keep it so I could play with my bro as well. I noticed it struggles easy with BFBC2 but I think with the ram it will make a difference.still, It supports max 8gb, but sometimes I notice the lack of cpu(you know when the processing get cuts and slows down). I don't know how much are these cpus,Im struggling to find some of them online.

I heard that the new i5 2500k is a great upgrade from the old quads, so it must be darn fast, and the price is acceptable. I don't know if would be worth it to wait and save for longer to get the i7. Do you have any of them?

That is good ram fur sure if you want to get it.

I have the i5-2500k, upgraded to it from a Q9300. I can say that the Sandy bridge CPU is truly amazing both in it's effieciency, cost ratio, and sheer speed, not to meniton awesome and easy OC.
