Hey guys, looking for some help regarding an upgrade on my machine, I usually game exclusively on my consoles nowadays, but what with Star Wars: The Old Republic coming out and me being a SW/MMO nut, I've no option other than to play it 
Current system:
E8400 @ 3ghz (Stock) (Cooled by noctua UH-12P w/ 1 Noctua fan)
Asus P5N-E SLI
ATI 3450 (Cost £27 new after my old 4890 OD'd itself too many times and was sold!)
4GB OCZ Gold
60GB Crucial SSD
2 x 750 Samsung F1 750GB
SB X-Fi Music
650W Corsair Modular PSU
All in an Akasa Eclipse w/ 120mm Noctua front & rear fans
The main issue I'm not sure on, upgrade the motherboard & cpu or do you think they'll still hold out?
I've got about £500 max budget to spend and was hoping to bring the system sound down a bit on top of this, I really don't want a loud machine, was thinknig if I can get away with keeping the current cpu/mobo I'd buy another 4gb (or 8gb set, whichever works out well for the money) and a SSD for the few games I have for quicker load times & quieeter gaming.
Any opinions or specs would be great..(Might sell off the 2 750's and throw a 2TB in at some point, too!)
Thanks!
