Windows 7 x64 would enable you to use all of your RAM, whereas Windows x86 limits you to around 3.5GB after addressing the memory of other hardware. Do not expect much, if any, performance increases in Windows or running applications over Windows XP, though.
Regardless, note that Windows 7 RC is still available, so you may consider downloading a free copy and taking it for a spin (dual-boot with Windows XP) to see if you like the features that have been added the past 7 years.
See the forum sticky for details.
Hope this helps,

Ok Folks I just have a simple question for the super geeks out there. Would it be beneficial to replace my 32bit XP w/ Windows 7? To be honest the only reason I think it might be is because of the fact W7 is 64 bit the way I understand it and I'm thinking that would give my system a little bit more power?
Here's all my stats:
Dell XPS 700
Processor: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz (2 CPUs), ~2.4GHz
Memory: 4096MB RAM
Hard Drive: 244 GB
Video Card: NVIDIA GeForce 7900 GTX
Sound Card: Speakers (Creative SB X-Fi)
Operating System: Windows XP S3 32bit
If you need more info please let me know and thanks in advance to anyone who gives me a hand.
