How Important is Memory Interface?

I'm looking for a new video card and am wondering how big of a difference one can tell between 128-bit and 256-bit memory interface. All I plan to do is normal web browsing and game some. The 2 games I'll play are Star Craft II and The Old Republic. Screen resolution will be at 1920 x 1200. The cards I'm considering are the Radeon 4870, 5770, 5830, and 5850. The rest of the computer is as follows:

AMD Phenom II X4 965
GIGABYTE GA-890FXA-UD5 motherboard
G. Skill 4 gigs of RAM
Corsair 650 watt Power Supply
500gb hard drive

Money isn't a huge factor but if I can save some, then more power to me.

5850 has to be the card for you since u want to play starcraft 2 at full hd res.At high res mem bit becomes a important factor so 256bit cards are the best.

Thought so. Thanks for the fast answer!

If you don't use AA then a 5770 will run SC2 with everything on ultra easily, it's not that demanding for GPUs, more so for CPUs.
