Someone explai in laymans terms (Graphics)

What matters at the end of the day is bandwidth. Bandwidth can be calculated my multiplying the Effective Memory Frequency by the bus width.

To calculate the effective memory frequency, multiply the frequency by 2 if its DDR3 or 4 if its GDDR5. Most of the figures you see in advertisements will already do this. For instance, a 5770 uses GDDR5 running at 1200MHz, but the effective memory frequency is 4800MHz because GDDR5 can perform 4 operations per cycle. DDR3 only performs 2, so 1200MHz DDR3 effectively runs at 2400MHz.

Bus width is pretty straightforward - higher is better.

Eish dude, E8200 will make a nice difference. What is your budget for a GPU? Can't believe you are playing SC2 max on that screen. :D

The 460GTX has 2 versions - a 768mb and a 1GB - the 768mb ones go for around r2000 - the 1gb versions go around r2500 ish.

Where did you find these prices? I'd be very happy to find a 1GB version for R2500. However everywhere I look the 768mb cards go for around R2500 and the 1gb versions for around R3000.

R2000-R2500

what do you mean by Can't believe you are playing SC2 max on that screen?
 
if OP only really plans to play SC2 then a R1k card is all he needs really.. But a 460 @R2k would keep you running games for longer :)
 
Bus width and memory speed are really not the most important things - it's similar to how much ram you have vs what speed your processor runs at - ram is only useful if you have a fast processor. Core clock speed, ROPs, memory speed, etc - that's what actually directly affects the GPU power.
 
As was said earlier. If all you want is to max sc2 you can get a 5750 for 1300 from prophecy.
