If you did not buy it form a retailer like hp or dell, I would consider overclocking the cpu. Intel Core 2 Duo's are much easier to overclock than a quad core. But Brand name computers do not allow you to overclock. Also, you can overclock the gpu. But for a good upgrade, you may want to change out your gpu for something like the "MSI R5770 Hawk Radeon HD 5770 1GB" or the "EVGA GeForce 9800 GTX+ 512MB". These are both great video cards and a nice upgrade. Or you could upgrade your Ram to some G.skill 4gb memory.
No its my build, so u think i should overclock my CPU problem is i have never i over clocked a CPU i have heard u can overclock a E7500 to 3.00ghz with stock cooling is that true and how can i do it without damaging it and by the way whats the difference between 9800 gt and 9800 gtx
I think you can get a slight overclock with stock cooling but you should definitely upgrade to an aftermarket air cooler from a reputable company like Zalmann. You only need to spend about 40 dollars. However you could go even better and install water cooling, but I think air cooling is the best for your situation. With aftermarket cooling, you could easily get it to 3.5 or 3.7 ghz. But a thing to remember is to only adjust one thing (fsb,cpu multiplier, voltage) at one time. Head to the overclocking section to find help on your processor or post your own thread. P.S. The difference between the two gpu's is the 9800 gtx performs 15% better. However, if you overclock the 9800 gt, you can get the same performance.
