I have an old d975xbx lying around and I was hoping to get it up and running with a few components.

The mobo is an older revision, so it supports only older dual-cores. My plan was to get:

-An E1400 CPU (I could get an e4700, but it is 100$ more...)
-An XFX Radeon HD 4870 1GB DDR5 PCI Express 2.0 Video Card
-4GB DDR2 667 ram

I am worried there will be severe CPU bottlenecking...what is the best GPU I can put in to max out the gaming performance I can pull out of this old mobo?

Thanks for the help in advance. :)

What resolution will the games be played at. I don't think there will be "Severe" Bottlenecking. A HD4870-5770 might be the max for that cpu depending on the resolution. Also you could overclock that cpu a bit which would help.

Thanks for the reply!

I was hoping to fill out my 23" 1080p monitor :)  [1920x1080]

Also, I must tell you I am a total overclocking noob. Never done/attempted it. So that may not be an option unless I get a friend to do it.

So you don't think there will be too much bottlenecking?

Is there any tool I can use to estimate how a specified machine will perform in certain games? Something where I can define the mobo,proc,gpu,ram,etc, and it gives me an estimation of the fps I would get? Sort of like Can You Run It, but allow me to define the specs of the computer.

Also, if I wanted to run a game like L4D2 or SC2 at 1920x1080 resolution, would I see slow down? According to the latest gpu charts, the gpu I am thinking of purchasing gets about 75fps in left 4 dead 2 at "1920x1200, 8AA, 16AF, Very High Quality, DX9". But, with the slow e1400 cpu, what do you think I will realistically get?

To give you some idea of what kind of gameplay you can get with a old E8400 dual core @3.0, read this article: It is not bad, and the graphics card is much more important.

That said, I don't think it is a great idea if all you can reuse is the motherboard.

Even the cheapest G6950 dual core will be much better and not cost more. You can get a 1156 motherboard for $80,
and ddr3 ram is actually cheaper than DDR2 today. Sell the old motherboard if you can and plan on something current.

geofelt has a good point, depending on how much your willing to spend on parts for your board might be better to get a new mobo cpu and have a decent gaming rig so your cpu ain't running at 99%

mobo + cpu just something you might want to take a look at
