Performance average of a few games:

Power Consumption:

So the GTX660 is a bit faster, while using a bit more power. If you game at >1080p, the GTX660 is better, if you game at 1080p or less, either one will work. The 7850 can generally be had for cheaper now days, I'd go with the 7850.

The MSI 7850:

The MSI 660:

The 7850 is 20 dollars cheaper right now (on Newegg.CA, only 10 dollars cheaper on Newegg.COM), and more frugal as well, but it is a bit slower. If you shop around, say NCIX and other stores, you might even find better prices.

Compute wise the AMD's current crops are generally better.

what about memory bandwidth issue with 660..........does it greatly affects it when gaming at 1920*1080 resolution..............

Not so much at 1080p unless you use more than 4X MSAA. Then the limited bus width becomes an issue.

Shouldn't be an issue at 1080p with most games and AA settings at moderate to max. The HD7850 has a bit more memory bandwidth (1200mhz x 4 transactions/clock x 256 bits wide > 1500 mhz x 5 transactions/clock x 192 bits wide).

FYI, the MSI 660 is really nice (as well as their HD7850). Runs very cool, and quiet as a whisper. All nickel plated heatsink (no copper left to oxizide after a few years) and PWM (4 pin) fans.

so should i pick 660 over 7850 for gaming at 1600*900 resolution..........coz at that resolution memory bandwidth wouldn't be an isuue........

Well, technically at that resolution, the HD7850 AND the GTX660 are both perfectly fine. I guess then it comes down to what kind of a sale price you can get.

The HD7850 can be had for cheap (2GB edition) like here:

For the money you are going to pay for a GTX660, you can get a HD 7870, like this:

http://www.ncix.com/products/index.php?sku=69557&vpn=AX7870%202GBD5-2DH&manufacture=PowerColor&promoid=1258

If you are bent on spending the 200+ dollars on a GTX660, I'd go with the HD7870 above. It is about the same price as a GTX660, and quite a bit faster.
