ok, i am planning to convert one of my old desktop into a HTPC... Specs are:

P4 2.4B GHz
ATi RS350 (Radeon 9100Pro IGP) + IXP300 Chipset
DDR400 1.5GB RAM
Radeon X1950GT 256MB GDDR3 AGP
currently running XP Pro SP3

main activity will be to watch TV, and occasionally DVDs... i ve the necessary softwares to take advantage of AVIVO, but i am more worried abt the CPU...

enough power to be a HTPC??
