How much gain by Win7 x64 / x32

(moderation:
Hallo !
I got a small notebook, that came installed with Win7x32 and on extra DVD Win7x64. This is, because the nvidia graphics card has no driver for x64 at now and there is no suitable CUDA 2.6 driver for this GPU. So, how much gain in crunching performance will give a change to Win7x64 ? The nvidia GPU is not necessary, as there ist still a Intel graphics processor onboard, which is sufficient for my purposes at this time.
Has someone experience in this regard ?
Many thanks in forehand

As far as I know, Einstein doesn't even provide a 64-bit application.
If you are interested in other projects doing that, there's a thread at the BOINCstats forum covering this topic.

After reading this I got a little worried. However, I suspect it is just a misunderstanding. I am planning on purchasing a computer that comes with Windows 64 bit. I know there is a 64 bit version of BOINC.
RE: CPU applications
Can most BOINC 32 bit (CPU) applications run on a 64bit Windows system? I think they can but I would like confirmation.
RE: CUDA applications
At the present time, the power supply (240 watts) of my future computer does not appear to be powerful enough to run a CUDA card. However, that may be possible in the future.
The stupid computer motherboard will only allow 4 gigs of ram, but still Microsoft wants to force consumers to use their OEM 64bit OS!

Yes.
Unlikely at present, possible in the future, but as much as anything else that would be contingent on science app designers making WU's that run acceptably fast on cards 50-100x slower than the highend.
I'm guessing, as much due to the tiny PSU as to anything else, that your computer is very low spec and only has 2 ram slots instead of the 4 or 6 standard on higher end boards.
that said, win32 would only let you use about 3GB of ram and with 2GB dims getting as cheap as they have 4GB is becoming standard on all but the lowest spec machines. Going forward this is going to be even more true. The rumor is that win8 won't be available in anything except a 64 bit version. The proliferation of mainstream computers with 4+GB of ram is making that seem more plausible now than when I first heard it.

Sorry, didn't mean to worry you. :-)
Your original question was:
and I only wanted to make clear that there would be no gain in performance (at least for Einstein) by changing OS.

Just to clear things up a little bit, all 32-bit apps will run on 64-bit. The only thing to be cautious of though is 64-bit requires 64-bit drivers.
I was gonna install Windows 7 Ultimate 64-bit on my main machine but I could not get 64-bit drivers for my Samsung Printer or Canon Scanner.

Canon MP640 by any chance? USB or network install?

Thanks for every ones help. I wasn't extremely worried because your comments mostly confirmed what I had suspected.
The 50 to 100 times slower CUDA cards was the biggest surprise. However that doesn't change anything. I now know I will not be doing any CUDA computing as long as I live in Florida & have to pay for air conditioning!
I may be buying a low end computer, but it is almost 4X faster than my present 2002 XP computer with an Athlon XP 1.7 Ghz processor, It uses SDRam memory!
To me, the Compaq Presario CQ5210F Desktop PC with AMD Athlon II X2 215 Dual-Core Processor (2.70 Ghz) will seem blazingly fast! And it uses the same wattage power supply!
Sorry for taking such a long time to reply. I forgot to subscribe to the thread. I was wondering why I didn't get any replies.
Thanks again.

Some data points that may be relevant:
Performance differences, 32-bit Vista vs. 64-bit Windows 7
During the past month, I upgraded two old boxes
to i7-860's, 2X2GB 1600MHz RAM,
ASUS P7Q57-M DO microATX motherboards with
identical BIOS parameters,
modest identical video boards,
BOINC v. 6.10.18.
One box used the 32-bit Vista install from
the prior Pentium 4 occupant.
The other used a new 64-bit Win 7 install.
Benchmark and Approximate process time Differences:
A. 32-bit Vista, effective 3 GB RAM.
Benchmarks:
Total Integer speed: 60.89 GIOps
Total FPU speed: 22.35 GFlOps
Elapsed Times:
Arecibo Binary Pulsar Search (STSP) 3.08: 3H34M - 4H06M, Avg: 3H50M
Global Correlations SS Engineering 3.04: 6H55M - 7H01M, Avg: 6H58M
B. 64-bit Windows 7, 4 GB RAM.
Benchmarks:
Total Integer speed: 73.65 GIOps
Total FPU speed: 20.45 GFlOps
Elapsed Times:
Arecibo Binary Pulsar Search (STSP) 3.08: 3H51M - 4H26M, Avg: 4H15M
Global Correlations SS Engineering 3.04: 6H52M - 6H55M, Avg: 6H53M
Conclusions/Curiosities:
On the "native" 64-bit OS:
- GCSSE work was processed slightly faster
but the ABP significantly slower.
- The Integer benchmark improved 20% but
the Floating Point benchmark degraded about 10%.
Benchmark correlation:
- GCSSE work seemed unrelated to benchmark values.
- ABP work improved with GFlOps values.
