Hi, I want to upgrade an old pc of mine for use as part of a home media centre. Its current specs are: Motherboard: CPU Type Celeron, 3066 MHz (5.75 x 533) Motherboard Name Dell Inc. Dell DV051 Motherboard Chipset Intel Grantsdale-G i915G/GL/GV System Memory 502 MB BIOS Type Phoenix (04/04/06) Soundcard: Creative SB X-Fi I'll be running XP Pro (or maybe Vista HP if it runs smoothly) and streaming to an XBox. I don't want to spend too much money and I saw this kit online AMD Athlon 64 X2 5200+ 2.6GHz Socket AM2 1MB, BOXED m/koeler MSI K9N6PGM2-V, nForce430+GeForce 6100, Socket-AM2+, m-ATX, DDR2, LAN, PCI-Ex16 Corsair Value S. PC5300 DDR2 2048MB Kit w/two matched Value Select 1024MB The kit including delivery is €138 ($183 USD). My question is, can I fit this kit without changing my motherboard, and if not, would I be better off getting an Intel Pentium Dual-Core processor such as Intel Pentium Dual Core E5200 2,5GHz, (€79 E, $104 USD) and add the graphics card and memory separately. I really want to keep cost to a minimum, and make the upgrade to a dual-core as hassle free as possible. Any suggestions and help would be much appreciated. Cheers!
