lol, where have some of you been the last few months...
Windows64 came out a while ago, its a free trade in for windowsxp pro owners.
Im not sure why most people would want it, since all it really does is add support for over 4 gigs of ram- so if you arent running a server...
Athlonx2 dominates the pentiumD pretty much hands down, most importaintly in heat (or lack thereof)
PentiumD with hyperthreading has been out since may, its called the extreme edition- a worthless waste of money. When you already have 2 real cores, adding 2 imaginary ones is pointless for anything you would be doing on a desktop- the benchmarks can attest to this.
But I digress...
If you are getting a 64 (single core), make sure you get a venice/sandiego-They overclock way better than the previous winchester/clawhammer cores (mine hit 2.8ghz on the stock air cooler) and have better memory support even if you arent ocing.
Best motherboard hands down is the dfi nforce4 ultra D or SLI.
Make sure you have a power supply (24pin) that can handle the 64.
Apples age better. even old ones can run the newest software and OS's no problem.
Normally I would agree, but with apple switching over to x86 (intel), this will not be true for apples bought now- 2 years from now, new software for current apples will be hard to come by.
The nice thing is that if you go with a x86 box now, you can probably switch to osx. There are pirate types that already have pre release versions of x86 osx running on their pcs.
