AMD CPU's are preferred here.
I bought an Intel last time, because I was sick of Intel fanboys blaming every problem I had on my CPU (like any CPU does anything but add 1's to 0's).
The 2.4GHz Q6600 clocked at 3.5GHz (in fairness, the best I ever beat out of an AMD was 3.4), and is SERIOUSLY sluggish.....once it bothers to DO anything at all, it's fast as fuck, it's just waiting on it to actually start. Built another couple of machines with Intels for others, and ALL their Quadcores do this shit. Built a couple of AMD boxen for poorer people (intels cost fuckloads more), and it was like a breath of fresh air...."see how I click the button and the machine responds without a committee meeting Batman"
Still can't see how it's CPU related, it must be in (all) intel quad supporting chipsets (Or in Macroshafts CPU microcode drivers, because it's a lot snappiER in Linux).
Nvidia cards beat ATI's to death.....although they can sometimes perform very well, and certainly offer more bang for buck, their drivers in every OS are spectacularly buggy, painful, and no fun at all to use.
The only Nvidia product I would avoid is their intel chipsets......I had an Asus StrikerII Extreme, and as well as being bonkers and unstable, with massive FSB range holes....it basically just turn electricity in to heat. When it finally went dead I replaced it with a gigabyte board with an Intel made chipset......infinitely cooler, and actually stays stable. Their AMD chipsets USED to be good, but I dunno about now.
Windows7 is a big step forward, it wont be long before it catches Linux in terms of hardware support and interface design (it takes MS AGES to nick KDE and Compiz's ideas and even longer to make them work in the legacy environment). It's almost there already in terms of ease of installation....although it takes far too long and you get exactly 1 broken web browser, 1 unfit mail client, a media player that can't and a couple of desktop wallpapers, in about 20GB, not quite the 3000 odd programs you can get on a 1GB linux usb boot drive)
But sheeple will keep using it cos they have no choice. Good. If they ever changed Linux to suit fucktards who pay PurpleWorld 1500 quid for a 300 quid machine....I'd have to switch to FreeBSD (or Expensive OSX as the discapples of Jobs call it)
PS I only have 7 on a Vmware virtual machine because the crack uses Grub (the linux bootloader), and I've already got Grub installed and don't want to fuck it up. Oddly though it took 15mins to install on a (naturally very limited) virtual machine using VMware to do the install....but takes over an hour on the same hardware in native mode????????????? Proof positive that MS make it pause for a few mins every now and then to make you think you're gettin something.
Laptop is now Ubuntu, XP and mainly Gentoo
Desktops are now XP+Ubuntu and Gentoo+Ubuntu
No vista currently as my SSD is only 64GB, so I can only have XP OR Pishta OR 7....will use Linux to manage which is in place once I get round to installing Pissta and getting a good crack of 7.
