Both of those are significantly better performers.

Electricity bill is not a problem but heat definitely is... how much heat can i expect ?
 


In that case the 4850 only has a slight edge of the 6670. I would say buy the 6670.

It is cooler and quieter and has better driver support because it is newer.
 


Good catch. Though it's not a card you'll be cranking up the tessellation on it'll open up the ability to play DX11-only games in the future.
 
You don't understand how to do percentages? 30fps would become 34.5fps to 42fps based on 15-40%. You multiply 30 by 1.15 or 1.4. Smeezekitty gave percentages because they're a more useful/flexible measure than an absolute number of frames per second (which varies hugely by game, resolution and settings).
 
The 6670 is a better bet here. In simple terms 2GB of ddr3 is almost the same as 1Gb ddr5. Almost. Its better to have a 1GB ddr5 than 2GB of ddr3. I would say, if you can, look into getting something from the 7000 series. The 7750 is a cheap, lower power card that can get some good performance out if you are willing to spend the extra cash.
 

No, please. Don't conflate capacity with performance. 2 GB DDR3 is just as slow as 1 GB DDR3. And more than 1 GB VRAM is pointless with low-end graphics cards like these anyway. So 1 GB GDDR5 is significantly better than any amount of DDR3.
 


Which is why I said 2Gb ddr3 is worse than 1gb ddr5. Nowhere in there did I say go for 2Gb ddr3.
 
Sakkura is correct on this. It's pretty simple - if a game doesn't use more than 1GB than it doesn't matter whether it's 1GB or 256GB. But memory bandwidth absolutely will make an impact on performance, and at a given bus width and clock frequency, GDDR5 will push twice as much data as DDR3.
