GDDR5 is faster than DDR3 so get a card that has GDDR5 memory if you can afford it. 1GB vs. 2GB depends on what you are playing. Usually, 1 GB is fine for a low end card, however, the 2GB card you linked is the same price after rebates and DOES NOT require you to spend the extra $18 up front and wait 6 weeks for the rebate. It's a no brainer. Get the MSI AMD Radeon HD 7750 2GB GDDR3 PCI Express 3.0 Graphics Card R7750-PMD2GD3

^ JKatwyopc, the 2GB is GDDR3. OP dont buy it, the 1GB GDDR5 is much faster.

That 7750 does not have the power to use up 2gb of Vram.

The asus 7750 1GB DDR5 is the best one, and after rebate it's 97.99$

You can have 4GB DDR3, it's still no good vs 1GB DDR5, it's more important the memory bandwidths for performance.

I have a PCIe x 16 slot open, would that video card fit in my computer?

What is the difference between these 2 graphics cards? I also need the card that uses the least power supply because i have a 300 Watt on my PSU.

The problem now is, how am i gonna get 100 bucks... Any ideas?

What about this video card?:http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Also a good brand, a bit more of overclock from factory, but more expensive, all 7750 cards 1GB DDR5 are around that price.

Im not gonna overclock my GPU. So the ASUS HD 7750 would probably be the best choice? What computer do you have?
