Ok so I got bored at work yesterday and worked on this.
I know that brute force power will always grant more credit due to how quickly it gets through the work unit but it makes some interesting reading.
The GX2 is a bit of a false economy just now as its uses two of your cpu cores to run.
I would say that 9800 GTX+ looks to be best value for money for GFlops and Power Usage.
Anyone know how to find out what the average WU length is for each of these cards so I can add it in?

Quoted from one of the PS3Grid forum threads:
1. GeForce 280GTX: 25000 sec/WU
2. GeForce 260GTX: 28000 sec/WU
3. GeForce 9800GTX+: 44000 sec/WU
4. GeForce 9800GTX: 47000 sec/WU
5. GeForce 8800GTS512: 50000 sec/WU
6. GeForce 8800GT: 58000 sec/WU
7. GeForce 9600GT: 70000 sec/WU
8. GeForce 8800GS: 74000 sec/WU
This is estimated time (+/-2000 seconds ) of what you should expected from this cards when they operate at normal values.

I recently bought two Asus 8800GT's at £66 each brand new from Dino PC. That's got to be hard to beat for price.
The other thing to bear in mind is the number of streaming processors. Like you say, this gives you much higher processing rate, but at much higher cost.
I haven't put these new 8800GT's on online yet, but assuming they crunch at the same rate as the others I have, these new cards should be a bargain. Here is the actual outlay at chez Nightlord:
Asus 8800GT
£66, expected crunch time 14 hours, credit per day 5540
Zotac 8800GT
£89, crunch time 14 hours, credit per day 5540
Geforce GTX260
£183, crunch time 9.5 hours, credit per day 8165
So the GTX260 wins on credit, but is slightly more than twice the cost of the Zotac 8800GT, plus the cost of a huge PSU. However, the expected returns of the Asus 8800GT's should wipe the floor with all them in terms of return on investment.

Just a quick note to add, i was browsing the PS3 Forum and found the following query:
Hi,
I'm looking to buy a new card and I'd like to know if i should buy a
8800GT 256 or 512MB?
I found a 8800GT 256 at $60
What is the best for GPUGRID?
Thank you
Eric
The 256MB one should be fine for current version of the application, but we cannot guarantee for the future.

Which may suggest that if it needs more memory useage then the card might not be upto the job? Probably best to stick with the 512Mb to be on the safe side.
