1 - I was going to go with the Liquid Cooled Heatsink offered by Dell. One sales guy says it's compatible with Windows XP and another says it's not!
2 - Same story with the "nVidia GeForce GTS 240" and "nVidia GeForce GTX 285". One sales guy says it's compatible with Windows XP and another says it's not. Plus a few days ago when I went to select the "Windows Vista Home Basic / Windows XP Professional" bundle, it came up with an incompatibility error with the Operating System for both sound cards! I see since that they have taken the Windows XP option off the website!
They sure do have drivers for Windows XP for "nVidia GeForce GTS 240" in the drivers download of the website!
3 - Same story with the PCI soundcard. One sales guy says it's compatible with the PCI slots on the motherboard of the XPS 630 and another says it's not. I've checked the manual too and I 100% agree with you. I have it installed in a "Dell Dimension 8250 Pentium 4" and it works fine on the 8250's motherboard. This soundcard is only 2 years old and cost me €2,500, so you bet I want to use it on the XPS 630!
4 - Just one other question if someone can answer this for me it would be great! What's the difference between 630 and 630i and I don't see an option to select a colour for the 630 on the website. I want a black one!
