Hello any one and everyone who viewed this thread, and thank you for stopping by. Now i have a question for you.

I currently have a Gtx 460 1GB 256 memory bit.
I was looking in to getting a Gtx 660 ti but it has a 192 memory bit interface.

Now heres the question:If i were to upgrade from my 460 to the 660 ti would i see a good performance boost?(YES) Would it be worth it?(YES) What would the memory bit effect?

Thanks For helping out.

There is a link that can show you two gpu benchmark comparisons. I don't know much about computers, but hey it's a start!

Edit: Sorry the link I gave was for older gpu's, if you navigate the website it shows benchmark comparisons for newer gpus as well!

You'd see a very large performance benefit. I think the 660ti is roughly twice as fast as the 460 (which if my memory is correct is somewhere around a 6850 performance-wise?)

I don't like that they crippled the memory bus on the card, but that should only be a problem at resolutions above 1080p and in the future with SLI.


So the memory bit effects The resolution? I play at 1080p (1920-1080). Would it be possible to keep my 460 and use it for resolutions that are higher? If that's even possible of course.
And thanks for the Wonder full answer.

Yes, the memory bus cripples the card at higher resolutions and it also has an affect when AA is cranked up. At higher resolutions, the card is using more memory and having to send more information over the memory bus - so when the bus is crippled down to 192 bits wide, it starts to slow the card down relative to similarly powerful cards that have a much wider memory bus (e.g. the 7950's 320-bit memory bus).

Your 460 is too weak, though, to play above 1080p. You can't just compare the memory bus on the two cards - they are completely different chips. So, the 660ti would still be far superior at 1600p than your 460, even though the 660ti loses ground to a card like the 7870 or 7950 at 1600p.


Going through THG's review, I have a hard time calling it a "crippling" problem at high resolutions. Sure, it does lose some performance, but it's a small amount when moving to 1600p, not a crippling amount.

Look at all the benchmarks. It may fall behind about 1%-10% (I saw up to 7%) in relation to other cards at high resolutions, but not a crippling amount. It also depends on the game a bit. Some games had very little loss at high resolutions, if any, and at the worst case, you may have seen a relative 7% loss.
