No... You won't have endless driver problems with a 64-bit Win7. It was a bit of an issue in the early Vista days, when hardware makers had to scramble to make 64-bit drivers for hardware (despite Microsoft telling them well in advance that this was coming), but they've had a couple of years to work that out.
That's not to say there won't be times when some bit of hardware won't have a 64-bit driver, but I actually look on this as a good thing. If the hardware maker isn't confident enough in the product to produce 64-bit drivers for it, then it's probably just a headache waiting to happen anyway, and I'm better off without it.
The main advantage of a 64-bit OS, is that when combined with a 64-bit app, you can break the "4GB barrier". A 32-bit OS can only address 4GB of RAM, and due to some boring technical details, about 0.5GB of that is reserved. A 64-bit OS can use somewhere around 2PB (petabytes... That's the next order of magnitude up from Terabyte) if I'm remembering my figures correctly. But the exact figure isn't important so much as the fact that it's significantly higher than a 32-bit OS.
Nothing about it being a 64-bit OS really makes it faster as a whole.
I look at it more like preparing for the future. Similar to ripping the band-aid off now, and dealing with the teething pains sooner rather than later. If you're getting a new computer, you probably won't have any better opportunity to make the jump. You have to reinstall apps anyway, and do all kinds of adjusting to a new OS, reconfiguring things, etc. Since you run Photoshop, this is a great way to be able to break the 4GB barrier on that app, which can be pretty memory hungry. I think Adobe will send you a copy of the 64-bit version of Photoshop if you have a licensed copy of the 32-bit one. There may be a small processing fee, but given how much that program costs, it's a real bargain.
I am about to buy a new Windows 7 computer. I have to decide whether I want a 64 bit or 32 bit o/s. I will run Office, Photoshop and some not very demanding games along with Media Player. What is the difference? I gather that 64 bit will run faster and according to a post on this Forum dated August 2007 there will be endless problems with drivers. Is that still the case? Any advice would be appreciated.
