Hello, this is my first time building a PC and I was wondering if someone could give me some advice in if the parts are compatible or in if they are good enough.
This is what I'm planning to get:

CPU: Intel Pentium D 945
MOBO: NVIDIA nForce 780i
Video Card: BFG Tech GeForce GTS 250
Memory: OCZ Dual Channel (2x2048MB)
PSU: Cooler Master eXtreme Power Plus
HDD: Western Digital WD10EARS Caviar Green
Fans: Ultra Performance 120mm Case Fan
Case: Ultra X-Blaster

I'm trying to build a good gaming PC at an affordable price.
Also I would like to know for how much should I sell my old computer. The buyer wil most likely use it only for work; for applications like Windows Office and IE. This is the computer in question: Compaq Presario SG3102LA

Thanks.

It'll probably work but it's not going to be a gaming machine because it's a 4 year old processor to start with and that board isn't listed as supporting any Pentium D processor in any case.

What is your "affordable price"?

For now, I can't spend more than $500 in the internals so I'm not exactly looking to be able to play games like Crysis at full settings but to at least be able to actually play them.
What processor should I get then? Which one would work best for games: a dual-core of 3.2GHz or a quad-core of 2.8GHz?
As for the motherboard, is it a good one? or is it at least compatible with the video card? Cause it says that it only accepts DDR2 memory but I'm not sure if that also applies to the video card.
Sorry for all the questions but I don't know anything about computing and I don't have another place to ask.
Thanks.
