Hello all I am looking at upgrading my PC as it is slowly but surely coming more unstable as it is now 4 years old. Here are the Specs

• System Manufacturer: Gigabyte Technology Co., Ltd.
• System Model: GA-MA785G-UD3H
• Processor: AMD Phenom(tm) II X4 940 Processor (4 CPUs), ~3.0GHz
• Memory: 4096MB RAM DDR2
• Available OS Memory: 4094MB RAM
• Radeon 5870 GPU

The first thing I want to upgrade is the motherboard and processor and I want switch to a nice I7 processor and get some DDR3 ram as well so I was wondering if some could recommended a good motherboard and processor for the Motherboard I am looking at spending 200 250 USD on.

Thanks In advance Time_Lord
