"I have a core 2 duo e6300 1.86 ghz and I want you to tell me what graphic card ( affordable and has a good performance ^_^) should i buy to play the latest games like Crysis2 and call of duty black ops " - Well, my 5 PC's (2 x E6400, E3300, E7500, quad core i5-760) - All these PC's play both games real easy - you're right to ask about a suitable GPU, because thats where you get most benefit. My suggestion is check your Power Supply first, then available slots (can you fit two-slotter video card in the mobo?) Then start with a Nvidis GTX560Ti and work downwards towards a GT430 until you find a cost/power/size fit.
