Best Currently Available PC Motherboard And Processor Combo

[Royce]

What is the most desireable (fastest) currently available PC motherboard and processor combo out there, and can i exchange them and keep the rest of my system the way it is?..My current system is as follows:


Windows XP Pro SP2
ASRock ConRoeXFire eSATA2 Socket T Motherboard
Intel Core 2 Duo CPU E6400 @ 2.13Ghz
3.00 GB Ram
2 x Seagate 7200.10 320GB HD in raid
1 Seagate 7200.9 300GB HD
Audiophile 192 Soundcard
Pioneer DVR 109 CD/DVD Drive

Thanks for any info on this..I know what results i want, but i'm not sure HOW to look for what i need to make that happen. (I hope that makes sense)
