Hey Hardyz,
I'm also a computer nut although I wouldn't say I upgrade all that often (every few years). Theres 2 schools of thought, get the best bang for your buck today (mid-range performance) and upgrade more frequently... or upgrade once in a blue moon and go all out buying the most expensive stuff, I subscribe to the latter. I'll just say I've spent more than $700 on a video card more than once lol. It wasn't too long ago I built my most recent machine and it seems technology changes so much you need to start your research from scratch each time you build one.
I'm a big fan of AMD, in fact the last Intel I owned was the P90 chip that had the floating point error / rounding error... since then all have been AMD chips until now. Just like Xclio pointed out, Intel is not only pulling ahead in performance but they have finally come down in price to be very competitive making your choice a difficult one. Historically AMD has been able to keep up with Intel's speed closely (not quite as fast on the top end but close) and been a LOT cheaper... thats changing now though.
The best thing i can suggest is spend lots of time on the fourms, look up shootouts, compaire prices etc. and read up on items you're thinking about getting. Sometimes there's known driver issues or conflicts with particular hardware... Look for reviews items etc. Don't skimp on your Mobo, that is where you get to really choose what "options" are on your computer. If you a value minded consumer and looking to just use the PC for word processing and an 11 year old 2d game (UO), no sense going all out, get yourself a pre-built package or at least a Mobo with integrated features... I'm generally against integrated things like video however theres no sense over-buying for what your using the computer for.
Hard Drive Speed will affect boot and load times considerably (10,000 RPM drives like the Raptor load windows very fast)
Stay away from Vista if possible and I would suggest sticking with 32 bit to keep things simple
Video Card selection can be one of the most influential things on how fast your computer seems
More Ram Is Better up to a point... Don't skimp on ram but recognize there tends to be a problem with windows handling more than 2 gigs nicely (personal experience at least)
Intel / AMD doesnt matter, go on bang versus buck and remember this dictates motherboard.
Don't skimp on a motherboard, if you cant find the right mobo for your chip, find a new chip.
Integrated sound seems to be fine, all boards are standard with decent surround sound and no sense wasting $100 on a soundcard these days
All that said, after researching like hell for a few months I've got a great rig with a problem lol. Randombly after as soon as just 1 min up to as long as 6 hours, my computer either totally freezes or BSOD's or just reboots randomly. Not sure if its a conflict, harware failure, driver issue, ram, processor, HD... I'm stumped. I've run some programs to monitor for overheating etc. but haven't been able to suss out the problem yet. lol So what the hell do I know!
