crossfire or new graphics card?

I wouldn’t entirely agree with this, as I have tested two 5770’s in X-fire, and they matched the performance of a single 5870. I didn’t have a lot of time to do this, but they scored slightly higher than the 5870 in 3DMark Vantage and Metro 2033, and in Metro 2033 the fps was exactly double that of a single 5770 (with the same settings). The tests were performed on the same system, hence the time issue. Two 5750's should match a 5850, but have 2GB of memory.

My advice to the potential purchaser was the same, though – rather go with a less complicated single card than the X-fire setup, since it doesn’t always work as designed. If funds are limited, and you have access to a second 5750 at a good price, it is a viable option (just not in CoD at the moment!).

Pretty much my own experience to be honest. I had a single HD5870 and I sold it to get 2X GTX460s, when SLI worked they were great but a lot of the sims I play do not support SLI. In these instances when SLI was not working I really missed the extra power of my single HD5870.

Csou, could you let us know how it goes whatever you decide?

Sure thing. But here's what I am thinking. If I cam sell my graphics card at a reasonable price, I will then purchase a better card. If not, I will probably get thw same card(it cost 140 euros right now where I am(Greece)), and I am quite sure that the "devs" will work on crossfire very soon. Eitherway, I will let you know when I decide. I will wait for a couple of months in order to get a better price.

I am reluctant to purchase a new graphics card because i will have to throw away my old graphics card.

I have the same card and will being buying another for crossfire on high settings with a rez of 1440x1050 I am getting 21 fps 200 feet off the ground over london ..just about every where else i am getting 40+ fps.
CLoD is the only game that gives me any kind of problems, i play BC2 at max settings with no problems
So once they work out all the bugs aand fine tune the game 2 5750;s should handle the game just fine...and with out breaking the bank.
here is a review to give u an idea of what 2 5750's can do

here is an overclocking guide for the 5750

Hmmmmm.....

So, I've got a 5870 that works just great. I've been thinking a bit down the road too.

I think you have many options with 5770 and I think you should wait unitil Crossfire comes out in this sim, so we can see what the "real" performance in a sim is.

The sim community is littered with "poor hardware" choices made by folks who have based their choices on FPS tested products. Several years ago (in fact I think it was 2007) - Tom's Hardware used to publish testing results of FSX and rank the cards. Il2 and other sims scaled very similar to FSX - and you could pretty much rely on the test. But not any longer.

One of the things we are missing is comparitive testing within the CoD community on how these systems all scale.

There are many choices:

1) Double up on your existing card (another 5770)
2) Buy a 6970 and sell your 5770 on ebay
3) Pick up a 5870 2 GB at a good price (kind of hard - I wonder why)
4) Go Nvidea (if you can find a 2GB - Single GPU solution).
5) Wait a few weeks if not less...... (recommended)

Right now in CoD, with todays software - I can smoke a 6970 with my 5870. Why? No artifacts, no underclocking and who knows whatever else. This is what I'm seeing a lot of from 6000 series owners on all boards.

If you wait just two or three weeks, I'm sure you won't be sorry. Then at least we should be able to get some benchmarks from Crossfire in either CoD or RoF as both developers have announced that Crossfire is coming soon.

S!

Sorry, I misread your post. I thought you had 2x6990's.
