True, but then such extra costs are not really that much these days given so many boards do support CF and/or SLI at good prices (especially for older CPUs such as the Q6600, eg. Asus P5N 32-SLI Premium is about 35 UKP), and gfx cards now use so much power that a decent PSU is a wise buy anyway.
Ah, but we're not comparing today's prices. Your argument assumes we're comparing prices from two years ago.
mapesdhs :
Either way, like you say, I've obtained a good speedup for less than 50 UKP, reaching a level that will beat a 4890 or 5770 in many cases.
This I'm unclear on. Does this mean you've had the first 8800 GT for two years, and only recently bought a second card for SLI? If this is the case, nobody will criticize that move, if you've already got an 8800 GT and an SLI mobo, then buying a second 8800 GT is the best bang for your buck upgrade you can do. But If you're starting out right now--based on on US pricing, and I don't have the time to be a UK pricing expert--I'd choose dual 4850s or GTS 250 cards. Far better value there.

... Why are you assuming *your* prices are the only ones that matter?
They're the only ones that matter to me. I never said they were the only ones that mattered in some objective sense.

Fair enough, but if this is the case don't criticize me for quoting the prices that matter to me.
Jabs like "the world is bigger than the USA" aren't necessary, I'm sure you could think of a nicer way to make the point.

Anyway, my new question. Am I right in thinking that a Radeon 4890 should stomp on an 8800GT? (single cards I mean, never mind 8800GT SLI) I thought this
would be the case, but my friend's system - an i7 930 with one (now two) 4890s - isn't seeing the kind of performance I would expect. See:
http://www.sgidepot.co.uk/misc/pctests.html
I know these are 3DMark06 results and so the overall scores are not that meaningful since they're skewed by CPU speed, but the fps scores for the individual tests (Proxycon, Firefly, Canyon, Freeze) ought to be at least vaguely useful comparisons, yes?

Depends on your objective. 3DMark is almost completely useless for people making purchasing decisions, it is inconsistent and misleading. At best it's a vague relative performance gauge but frankly I put no stock in 3D Mark results, it is rare that game performance correlates closely to 3DMarks. If you want to know how cards perform relatively, you need game benchmark results.
If you're using it as a tool to see if his rig is running correctly, then it might be a bit more useful yes--but only against other machines with the exact same graphics setup. But in order for the data to be useful you first need to be exactly sure that the tests you're comparing were run at the exact same settings.
I'd be more interested in seeing actual benchmark data in your friend's case. It would be a much better indicator if something was wrong or not. The Stalker: Call of Pripyat down-loadable benchmark will be more useful for this kind of troubleshooting.
