Hello robin banks;
You're talking about video cards but you didn't mention what resolution monitor you're using.

Did they add Crossfire support to TDU 2? It was missing in the first version of Test Drive Unlimited..
Without Crossfire/SLI support 2x 5770s will perform like 1. So a 5850/5870 would be a major improvement if that's the case.
Find a Test Drive Unlimited 2 specific gaming forum and ask there. You want to be sure about CF/SLI support before you buy.
Do the same for Formula1 2010. I know that game is Xbox port and they have a reputation for power Crossfire/SLI support.

Well robin banks,
You need to tell what exactly is your resolution is,and with larger resolutions consider the more video ram you might need.

If you have no other cards under consideration:
Then preferably 5770 x 2 is the cheapest solution.Since the 5770 x 2 equals or at times outperforms the 5870
it is best to consider that at lower budgets.But still there is lot of other things you need to consider
ie.whether there is adequate powersupply and cpu processing power which can bottleneck your crossfire.

Since you told that presently you have a 555BE,it might unlock.Lets say you got it unlocked but still it might not be a perfect 955.
I think there can be cases where unlocked cores are defective to some extent or might be not.Also I mean it because you may not OC to those high clocks
as you might have done with the 555 after considering the stock cooler you will be using.If you cannot get your processor unlocked
then probably your processor can bottleneck your crossfire setup and i recommend a crossfire only if you get unlocked successfully.

The reason why many peole still recommend for single gpu instead of a slightly weaker card crossfired is that the a crossfired gpu solution can at times provide a lower fps when bottlenecked.Also there is a need for better power supply and cooling solutions as the heat dissipated under a crossfire setup is large due to 2 or more cards working at same time.Also a only a well ventilated chassis will do the good job.If you can't consider these then probably it is good to go for a single 5870.

Again if you compromise for lower resolutions go for a single hd5770 and later if you feel if it can't power up your games the way you like then get the next 5770.By that time you can get the prices down or you might have spared a little for the coolers.

still the battle between 5870 and 5770 x2 continues...
