Highest graphic card for Gigabyte SuperB 720W

Crossfire or SLI is generally a waist of time... A 5850 or a 5870 will easilly run on your powersupply - just make sure your card will fit your case.

The reason why i say crossfire and sli is a waste is due to the fact that the next generation of cards is as fast as the previous two combined, and is a waste of money imho.

Your PSU can easily handle HD5970. But do check if your budget can handle the card! Its a very expensive card. So if you can buy it, you have the most powerful card in the market right now!

from the sound of it, your entire system is rather outdated: 2gb of ddr2 667Mhz ram would imply at best an older socket 775 or AM2. Buying a video card thats high end might be a waste due to CPU limitations. also, does your motherboard even have PCI-express 2.0 slots? The new cards are backwards compatible in the older slots, but it would limit the card if this were the case.

While CPU limitation is usually minimal, knowing whether you have PCIE-2.0 or not is important because that directly affects your graphics card's bandwidth. Anywho, Depending on your computer's specs, I would recommend either a Sapphire 5770 or 5850.

+1 snurp.

What are the rest of your system specs, and what is your budget?

Its not worth spending $300-400 on a card if the rest of your computer is worth less than that.

I think the 5770($150), or at most a 5830(--releasing this week for ~$200) would be good options for you. Anything more would be power wasted on your PCI x16 1.0 slot.

Whatever money you have left over you should put in the bank for a new build soon.

If you save whatever single video card you buy now to crossfire in your next build you could probably put together something awesome for ~$600 or less.

ita not 1.0, its 2.0 revision 2 model

is it 1.0? i checked at gigabyte website doesn't show whether its 1.0/2.0. but i've been told that its 2.0 from a friend.

then i have to upgrade my mobo.

Oh, well that's good. You still haven't given us a budget of any kind though.

In order to leverage a 58xx card I think you would need to overclock your CPU. I'm not certain how the slow ram would impact your performance.

i've got $500 to spend but i'd like to keep the budget as low as possible. but the gpu is primary intention

the best value for buck is the 5850...


It isnt that far behind the 5870 and knocks loads of nvidia cards down and its dx11

later on if you go to a crossfire system then you can still use it..

In light of your budget I agree. A 5850 now, and then another when you get a new system.

actually now i am using 5750, is there will be a vast increase performance if i switch to 5850?i just wanting to know is it worth to switch to 5850.

It's an increase but not a justifiable 300 bucks imo as you've already got a 5750 which is fast in it's own right. If you had 2 PCIe 2.0 slots, you could buy another 5750 and run CF.
You could always take the $500 and upgrade your socket.

I'm just annoyed that you didnt tell us you had a ATI 5750 at the start. Helping you shouldn't be like pulling teeth.
