Hi Everybody,

I have around £80 - £100 to spend on a good card for doing CUDA work units. I would prefer a NVidia chipset.

Anybody got any good suggestons?

You are in luck since CUDA only works in NVIDIA cards. :D
Checking amazon.co.uk I see several GTX 250 cards in that price range. I don't know if you like an vendors better then others. I like to find a part I want, and then I will try to find it for the best price I can.

Yeah been looking at the GTS 250 looks like a good card!

I can get it for £91 :-) looks like ill be getting that then!

Or should I get 2 GT 240's for the same price which will crunch more WU's one 250 or 2 240's??

My choice would be the 250 & then get another 250 later when they become dirt cheap. That relies on being able to find another on later on. Which might be hard to do if everyone buys up the older cards when they get cheaper.

Just for the international friends..

This are 130.- / 160.- US$ or 90.- / 110.- €.

You should look also to your PSU which is installed in your PC.
Which you have? W and A ?


For this you could get a GTS250 (~ 100.- € / 90.- £), maybe ~ 7,000 RAC. If ~ 150 W max. power consumption, then ~ 110 W for CUDA.

For ~ 150.- € / 135.- £ you could get a GTX260-216, which have a better wattage/performance ratio. ~ 12,000 RAC / ~ 135 W.
But this GPU would need a ~ 520 W/36 or 40 A PSU. Depend of manufacturer and maybe OCed.

You could wait also little time to the release of the new Fermi GPU chip. GTX3xx series. Better performance/wattage ratio.
There is already the new Fermi out there, but 'only' GT210/220/240 with very 'low' CUDA performance. Like 8/9xxx GPU series.

I have a 1200W PSU with 4 6 pin connectors I went a bit OTT a few years back with the PSU! Im currently noly running a 7600GS which is ok for games but doesn't have CUDA!

I think I will get the GTS 250 and then another one a few months later :-)

I could be wrong, but I would guess 2x GTS250 = 1x (maybe OCed) GTX260-216.

If I compare my manufacturer OCed GTX260-216 with other GTS250, my GPU is double faster than one GTS250.

Hi Dan, I was going for the i7 860 and ended up with a i7 930 after advice here...Be careful asking here as some are pretty convincing and in my case I am glad. I agree on the GTX 260 BTW...

Yeah im just looking how much the 260's are I can bag one for about £130 Ive got the i5 750 in my rig the i7 was a bit pricey!

I got bit by the cuda bug, saving all my money for a 295 or new 300 series if they ever come out...

I see your runnig a 275, what credit do you get on average a day from that beast??

That I don't know as I built the machine with a 260 and put the 275 in before it peaked, I traded the machine this one replaced for the 275, so I got the overclocked one with 2 fans it runs in the 50's and still took a decent overclock...
I bet Sutaru Tsureku could take a look and estimate it if he chose.

go with the 260 gtx...

My BFG 250 OC running Seti Beta has peaked over 6000 on a mix of standard WU's (running Cuda only).

250 GTS
750.0 Mhz
1120.0 Mhz
1836.0 Mhz

71.7 GB/s
1024 MB GDDR3

As that is probably not the fastest it can go, as it is running a Lunatics hybrid CPU/GPU for VLAR's which take about an hour and ten minutes to process.

My/the GIGABYTE GTX260-216 SOC is + 25 % OCed than a stock GTX260-216 and + 3 % OCed than a stock GTX275. (AFAIK, the highest OCed GTX260-216 from a manufacturer)
It run at 680/1500/1250 [core/shader/RAM]

AFAIK, hiamps N275GTX OC run at 666/1476/1161.
AFAIK, a stock GTX275 run at 633/1404/1134.

O.K., the GTX260-216 have 216 shader- (27 CUDA-) cores, the GTX275 have 240 shader- (30 CUDA-) cores.
But, I would guess my run little bit faster than hiamps GPU.


The EVGA GTX275 FTW, ZOTAC's GTX275 AMP! and GIGABYTE's GTX275 SOC are also well for to look. Don't know the speeds.. but they are the highest OCed of the manufacturers.
But from what I read, the GTX275 go hotter than GTX260-216 (with the nVIDIA GPU case design). So maybe because of life expectation I would go with a GTX260-216.

To now, it wasn't mentioned in this thread..
..every GPU should get a PCIe 1.0 x16 (electric) or PCIe 2.0 x8 (electric) slot on mobo for max. CUDA performance.

Have you considered EVGA 9800GTX + ? you could get a pair of them (SLI).
Seem to be a lower cost and almost as good as 260GTX.
Getting ready to SLI a rig here with a pair of them.

But, power consumption of 2x 9800GTX+ <-> 1x GTX260-216 ? For the same RAC?

141 W max./~ 105 W CUDA -> ~ 210 W <-> ~ 135 W


If you crunch CUDA, you shouldn't use SLI (the newest nVIDIA_driver should disable SLI automatically if CUDA).

Actually that is my stock speed but I run the 275@739/1637/1188 so mine is probably a bit faster.....

Hi Dave I thought about getting 2 GTX275's as that is all a GTX295 is anyways but I only have 2 x16 slots and then that wold be all I could do. I want to add a 295 and keep the 275 and put the 260 into another machine as I figure it would be slower running at x4. Then it would be like 3 275's.
