A 6770(A re-badged 5770 with its 128 bit memory controller) Is not much(if any) upgrade from a 4870. I personally find it a tad slower.

Toms own charts(link messes the forums. had to link it this way)

I am not sure i would trust the WEI score as a good measure of performance

I know it is a pain, but yes. The 4870(You can see if it is a 4870 or 4850 with cpu-z under the graphics tab, there is even a 4830, but unlikely you have that one) was a high end card and the 5770 is a middle end card. The 6770 is just a 5770 with support for 3D glasses(with the right software)

By the time you need over the 512MB frame buffer, the card will not keep up anyway. There are some games that the 6770 will be faster in and others it will be slower in. I have both so have tested it fairly well. Overall i am impressed with the 5770(6770) for its lower power consumption and cooler idle temperatures. Its performance is good considering its limited memory controller.

Please ensure you have the latest drivers for your 6770 as my WEI(like it matters) is the same for the 4870 and 5770.

I was more talking for the old card to see if it is a 4870,4850 or 4830

cpu-z just shows info, nothing more

If you are happy with the 6770, just keep using it and enjoy

WHen getting an AMD card, you have four numbers. x x x x -- The first number is the series, basically what year it came out, later numbers are later years. THe second number is the performance level. the third is which part, upper lower or mid, of that performance level. So the 4800 series is older, but higher performing. The 6700 series is newer, but not as high up in performance. This will also be reflected when you see the 4800's cost much more. You will however have DX11 support in a 6700, because it's a 6xxx series. Though that doesnt really matter for gaming, as it is not a high performance card. It's more of an entry level performance card, with all the latest features, while the 4800 is a *almost mid range card, without the newest features.

There are a total of ZERO games the 6770 is faster than the 4870. 4870 outperforms in every game hands down. and by far.

There might be a case here or there. But yes, the 5770/6770 is slower then the 4870. (5-10%?) It's even worse if he has the 4890, but he mentioned having 512MBs of ram and I'm pretty sure all the 4890s had 1GB.

Basically that's a sideways slight downgrade. You really want a 6870 or better for an upgrade.

There are some games... not many, but some. I have both if you want me to review some games for you?

Here was an early review(some games even take advantage of the extra ram at high resolution). Drivers should have improved slightly

A quick google for some reviews gives you some tests to look over.

6950 vs 560 Ti(The ti is faster then the normal 560, but very easy to find)
http://www.tomshardware.com/reviews/geforce-gtx-560-ti-...
http://www.guru3d.com/article/radeon-hd-6950-1gb-vs-gef...

And here is a toms charts
The ti is slightly(or more on some games) faster then the normal GTX 560. Order on the chart GTX 560 TI | 6950 | GTX 560
