I'm going to agree with sharken. If it were me, I'd get a new chip and mobo. I don't think you'd get much value out of a high-powered GPU with that CPU.
Also, is it really necessary the TYPE IN ALL CAPS? Can't you just trust that we are all capable of reading these posts and will take what you write into consideration?
For your purposes, it all depends on your budget, but if you're not looking to spend a ton, but want to keep relatively current, a P45 and a decent Intel chip would keep it pretty cheap.
If you have more money to spend, a Phenom might be possible. I'd stay away from i7 right now for your purposes, because it would be like building a completely new computer and would probably cost you $1000 or more.
offense taken but its accepted, btw the CAPS thingi is for telling the stupid ppl my point i mean sometimes a get frustrated by ppl who think they r smart but what the hell i typed it anyway. ALSO (LOL) appreciate ur concern but u cant help me my country is very very $ive if u wanna see our prices and what hardware they only sell u will be shocked so before i give u my budget check this www.pcandparts.com
this is the cheapest !!!! if u see it u will see how frustrating
i know, so u see my options are to buy a bit decent mobo with a c2d like e6600 2.4 and oc that ( i saw good results 3.8 actually) but i will run out of $ for a gpu so u see what i was trying to do.
BTW i broght a 9800gt for a friend who has same system but his cpu is 3.0 (faster than mine) and some games work fine like grid but crysis warhead is unplayable in all setting on even 800x600 so a 9800gt is being bottlenecked by cpu LOL.
i know i am skrewed but wth gave it a shot. SUCKS to be me right
