Right well it's post-christmas and there are deals a plenty so it's upgrade time.
My current CPU/RAM/mobo are around 4-6 years old so it's time they became a server and died slowly
I have some ideas in my head, pretty sound but I want to know what would you recommend and why? The upgrade will not be performed again for a while but the performance must be high and future upgradability must also be high.
You have £400 to play with, what do you buy?
Current spec:
Skt939 AMD4000+ @ 2.95Ghz - Watercooled
2GB (4x512MB) Value CL2.5 ram
Gigabyte GA-K8NXP-SLI Mobo
OCZ 700W PSU
768MB BFG 8800GTX OC Edition - Watercooled
HDDs:
1 x RaptorX
2 x 500GB Seagate Barracuda 7200.11 RAID0
2 x 320GB Maxtor 7V Series RAID0
Cooling is performed by a half Thermaltake half custom Watercooling and does not have to be upgraded for AM2 or 775 sockets. Cost must include necessary watercooling improvements. A copy of Vista in the cost would also be appreciated
Edit: I just found 2GB DDR2 800Mhz OCZ Platinum 4-4-4-15 I didn't know I had, worth adding or best selling on for more cash?
