Need New gCard !!!

[voxom]

I have a Asus P5ND2 SLI Motherboard, 2gb of ram with a Pentium 4 Processor and 550W PSU.

The current graphics card overheated and wont stay on longer than 5 minutes. I want to be able to play things like D3 & Starcraft II while keeping the cost around $100. & preferably be in 1080p.

I'm seeing that most the graphics cards are DDR3 whereas my mobo supports DDR2, will the DDR3 graphics card be backwards compatible?

If i have 2gb of ram will i be able to use a 2gb graphics card or should i stick with a 1gb graphics card? thanks

The type of ram on the GPU does not need to match the system ram. The spec is listed because there are different types of ram for GPU's with DDR and GDDR being the two most common ones. (I dont think any of the other types have been used in a long while) GDDR being better than the DDR equivalent.
please note that these come in different speeds such as ddr2, ddr3, Gddr5...

The problem is that just about any decent graphics card is going to be bottlenecked by your P4 cpu which cannot run many modern games. Definitely not D3 though SC2 should at least install.

D3 & Starcraft II are very heavily CPU dependent, and favor intel chips greatly. You need at least a Haswell i3, and you can get a moderate GPU.
