Should I switch over to ATI Radeon?

I currently have a Core i7 920 rig with:

- EVGA X58 SLI LE motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and a EVGA GTX 260 graphics card. It appears that Radeon graphics cards are showing more promise recently. I am seriously considering purchasing a Radeon 5770 or a 5870 instead of buying another GTX 260 for SLI.

Does my motherboard support crossfire? I heard that all X58 motherboards support both SLI and Crossfire but I don't see it in the product descriptions. Has anyone had success mating the EVGA X58 LE mobo with Radeon cards? Single and crossfire??

If my motherboard can indeed support this, I think I may surrender my Nvidia fanboyhood and move over to the dark side...

Yes, until Fermi is released in March, ATI cards have the advantage of being both bang-for-your-buck and the best performing.

A 5870 is equal to a 4870x2, making it equal to two GTX260s in SLi and/or a GTX295. A 5970 is equal to two underclocked 5870s or two underclocked GTX295s. An OCed 5970 at $600 will demolish a GTX295 without breaking a sweat.


All x58 motherboards support SLi and Crossfire.

For the price of two GTX260s (~$380), you should either get two 4890s (which perform equal to two GTX275s) or a single 5870.

HD5770 is not an upgrade but HD5850/70 is!

^ Yep, if you can sell your GTX260, then get a 5850 or 5870.

If you can't sell your GTX260, get another for SLi if you can find one for ~$160

Ok, I double checked, this is for your motherboard.

I didn't think that board would support Crossfire, but I read through the reviews of it and found a person who bought it for CF and it worked for him:

"Pros: All Vista 64 drivers worked with no issues.
Looks great.
Good price point.
Crossfire works fine, though not advertised

Cons: Could use 2 more 2-port USB headers on board to allow for internal card reader plus case built-in USB ports.

Other Thoughts: All my research on crossfire vs. SLI tells me that for SLI to work, the mobo has to have certain features (like nVidia chipset) but the crossfire does not depend on mobo components. This board was not advertised as crossfire-ready, but the other boards in the series were. This was a little confusing, but I took a chance because this was $60 less than the next board up and this had everything I wanted in a mobo (couldn't see spending $60 for 2 USB ports and an extra network adapter.) "


As far as the 5850/70, they are great cards.

Huh.....deja vu....thot I answered this already. The 5870 would be a reasonable choice but the 5770 is a 10% downgrade from the 4870 or the 260. Can't see spending $180 to go 10% slower....and, no, driver updates won't solve the bandwidth issue.

But we don’t have that luxury with the Radeon HD 5700 series. The value of the 5770 in particular is clearly not going to be in its performance. Compared to AMD’s 4870, it loses well more than it wins, and if we throw out Far Cry 2, it’s around 10% slower overall. It also spends most of its time losing to NVIDIA’s GTX 260, which unfortunately the 4870 didn’t have so much trouble with. AMD clearly has put themselves in to a hole with memory bandwidth, and the 5770 doesn’t have enough of it to reach the performance it needs to be at.

If you value solely performance in today’s games, we can’t recommend the 5770. Either the 4870 1GB or the GTX 260 would be the better buy.

So here’s the bottom line for the 5770: Unless you absolutely need to take advantage of the lower power requirements of the 40nm process (e.g. you pay a ton for power) or you strongly believe that DirectX 11 will have a developer adoption rate faster than anything we’ve seen before for DirectX, the 1GB 4870 or GTX 260 is still the way to go.

The 5770 is the choice to buy from scratch but it isnt an upgrade over a single 260 gtx or an ati 4870.

in this case it probably is worth selling the 260 though, because it isn't worth buying another one for sli.

I would sell the 260 and put the cash towards buying two 5770's. only an idiot would buy another 260 at around the same price as a 5770, spend the little extra on another 5770 instead. What little you lost in fps you gained much more with future proofing.

Some guy on an internet forum telling me all x58 MB's support CF isn't as comforting as reading someone having 1st hand knowledge. Excuse my help.

Ahh, thank you guys. Thanks bystander... that helped me alot. And JackNaylor was claiming deja vu cuz he answered my same question that I posted on the motherboard section of the forum.

The 5850 is equal to GTX 260's in SLi, the 4870X2 is more powerful than GTX 260's in SLi.
You could get 2 5770's for the price of a 5850 & CF them.

The 5770 is OK for what is considered low (1680 x 1050) resolutions today. If considering the 5770 as futurproofing for DX11, expect to be disappointed....at least at 1920 x 1200 or above. The 5770 may have a DX11 label but it's already choking on Dx11 titles like Dirt2 which only have minimal incorporation of DX11 features. The 4870 and 260 outperform the 5770 by 10 % in DX9/10 and based upon THG's review of Dirt 2, neither of the 3 cards is going to be capable of playing DX11 titles with any significant incorporation of Dx11 features at resolutions of 1920 x 1200 or above.
