How are DELL computers for Ubuntu compatibility? I'm looking to get the Studio XPS 430 at £879 which has the following specs:

Premium - Intel® Core™2 Quad Processor Q8400 (4M Cache, 2.66 GHz, 1333 MHz FSB)
Graphics 1GB ATI Radeon 3870 X2 graphics card
6144MB 1066 MHz Dual Channel DDR3 SDRAM [2x2048 + 2x1024]
1TB (7200rpm) Serial ATA/100 Hard Drive

Am I going to have difficulty with this? I run a dual monitor system if it makes any difference. My current PC is dying due to motherboard failure.
