x86 to x64 & benching

Have a quick question..... When upgrading to x64 Win7 from x86 Win7, is it normal to see a 'drop' in gfx performance?
In the screen shot I listed below, I have my old score in the background (with the arrow pointing at it) that was with Win7 x86. The new test is with Win7 x64. Both were clean installs from a formated HDD. Is the score drop normal? Or do I need to look at something else? Only thing that was changed hardware wise was I clocked my cpu back from 3.5 to 3.4GHz. Would 100MHz affect it that much? *Toast :toast:

 

x64 or x86 ??

I'm downloading https://jaxx.io/downloads.html. It requires to know if my Windows is (x64) or (x86). How do I find out?

 

Windows 7 x64 not detecting GTX295

Background
I installed the 295 and it was not detected. So I downloaded 181.22 for Vista x64, but those drivers didn't work for gaming (CTD). So I installed a GTX 8800 and it was detected and drivers installed automatically from Windows Update.

Now I put the 295 back in, and it installed and was able to run games. However, the nVidia control panel was not available, suggesting that the drivers hadn't installed properly... So I deleted the drivers and rebooted. And... again it lists my 295 as a "Standard VGA Graphics Adapter" and a "3D Video Controler", but no drivers can be found by Windows Update.

Question
1) Is there anywhere I can download the Windows 7 x64 drivers and install them manually?

2) Any idea how I can get Windows 7 to recognize my GTX295 so that it can download the proper drivers.

3) Have you had the GTX295 install automatically in Windows 7 x64?
