more ram yes, more than 8 (or maybe 12 if you really wanna push it) no.
I'd personally sell you the following stuff:
- CPU: Intel Core i7 860
- CPU Cooler: Noctua CPU-Cooler NH-U12P SE2
- Mainboard: Asus P7P55D, Intel P55
- RAM: 4*2GB Mushkin XP3-12800
- System Disk: Intel X25-M G2 80GB (SSD)
- Storage Disks: 2* Western Digital Caviar GP, 32MB, 1TB (RAID 1)
- Graphics Card: ZOTAC GTX-275 AMP! 896MB DDR3
- Case: Cooler Master RC-690-KKN1-GP, inkl. Mesh-Grid
That should make for a pretty good performance at a still reasonable price. Also it's gonna leave some serious headroom for overclocking the CPU.
Obviously, you can alter stuff like memory brand, the case, cpu cooler etc (although in that particular case I'd really recommend the Noctua - it's whisper-silent and reeeally cool)
Don't go for 4GB RAM kits just yet.. once this really becomes necessary, I'm sure the prices for RAM will have dropped dramatically once again and you can get them for a sensible price.
So the best plan so far is to get a 6 slot mobo for 12GB total. 12GB (as 6x2GB) ram would only come to around £200 total, which is nothing. I can see no reason to skimp at all.
Getting a 6 slot mainboard means using Triple Channel RAM, which means going for the older (but still great) LGA 1366 Core i7 (the 920 probably, since its the only one without an outrageous pricetag). Now, while that's possible, it's not the best bang for the buck as far as I can work out. For that you'll need a more expensive mainboard and you'll "only" get a 2.66GHZ CPU for the same price as the 2.8GHZ LGA 1156 Core i7
But you do need more RAM to get the most out of it. Try to get the newer DDR3 ones though.
rubbish! you're not gonna be able to put DDR3 RAM in your current system unless you change the Mainboard to some weird LGA775 Socket board with DDR3 RAM (they exist but are absolutely, utterly useless.)
