Wow, thanks. I'll try that later on. But, would it be compatible with my computer? :o
Considering your current specs, I believe it may require the overhaul and upgrade with the new parts. My last overhaul (I listed my specs somewhere) costed around 380 dollars (including the new Power Supply, without it, just 350).
AMD CPUs and Motherboards are cheaper (hence why I got them).
You should aim for getting a Motherboard that supports dual channel DDR RAM (If going for i7) up to 1600 Mhz and if possible, USB 3.0 support for future purposes.
Here's my current specs:
CPU: AMD Athlon II X250 (2 CPU, can be overclocked)
GPU: MSI GTS 250 1GB GDDR3
Mobo: Gigabyte GA-MA785GMT-UD2H
RAM: 4GB DDR3 @1600
Monitor: About 20 in. @ 1680x1280 Pixels @ 60 Hz
HDD: 300GB SATA (This is old and I may get new one when time comes I need it)
OS: Windows 7 Ultimate
Budget: The video card was on sale for $120. Motherboard was only $70. The RAM costs $100 (2x2GB Kingston Gaming DDR3 RAM @ 1600 Mhz). CPU was $60 (I suggest to get one of the newer AMD Phenom Duo Core/Quad Core models but those are pricey).
EDIT: Running this rig on 64-bit - The system can run any game I throw at it on High/Max settings (Including advance features like MSAA/CSAAx8 or x16; Vsync On, etc.).
