[Dopeway]

Hello, I am looking to upgrade my CPU because it is the only thing which make some of my games run like sh*t.

I was wondering which one, and what kind of CPU. I'm not looking for thé best, but for a decent one. If possible a cheap but still an awesome, fast CPU.

My computer :
- Windows 7 Ultimate 32 bits (6.1, build 7600)
- IMEDIA A7077 BE
- Default system BIOS
- 4096 MB Ram
- DirectX version 11
- Nvidia GeForce GTX 260 (total memory : 2032 MB)
- AMD Phenom(tm) 9100e Quad-Processor (4CPUs), ~ 1.8Ghz

If you need any more information just reply.
Hope you guys help me out so my pc can even go faster .

Grtz, Dopeway

Can you find out which motherboard or chipset your system is running. CPU-Z should be able to get this info.

What's your price range for the new CPU?

A possibility:
AMD Phenom II X4 940 Black Edition Deneb 3.0GHz Socket AM2+ 125W Quad-Core Processor HDZ940XCJ4DGI

You'd need to get a heatsink for the new processor since it's an OEM chip.
