Need help upgrading my computer

[ewoglightstar]

Hello, I have a desktop PC that is about 3 years old. I'm highly anticipating the release of swtor, but am worried about it running on my old system. I have about 400-500$ to spend on new parts or whatever I need. My Current system is as follows -
Motherboard - Biostar gf7050v-m7
Processor - Intel core 2 duo e6750
RAM - 2x 2GB DDR2800 MHz
PSU - Cooler Master 500w
Video Card - Nvida Geforce 7900
HDD- 1TB Western Digital Caviar black
Also have a no name DVD drive

So what recommendations do you guys have?

Your current PC exceeds the minimum requirements (but not by a lot). So, technically you don't need to spend any money if you want to play the game. You may even want to wait until you have the game and see if you are happy with the graphical quality. If you aren't then you can upgrade.

The cheapest and probably most effective cost effective upgrade would be to upgrade the GPU. You could go up to a Radeon 6870 for ~$150 - http://www.newegg.com/Product/Product.aspx?Item=N82E16814102948&Tpk=Sapphire%20100314-3L%20Radeon%20HD%206870%201%20GB

This comes to $535 and if you can swing it I think this will get you almost to a whole new computer. If you need to not go over $500 then sbstitute for this MB.
