Hi all
So I went and did a little speccing, I'm waiting for a quote at the moment.
Intel Z77SL-50k M/B
Intel I7 Quad +HT 2600 CPU
3 x 1TB Hard Drives
2 x 4GB DDR3 H/D’s
Corsair 700W
Windows 7 Professional 64bit
Cooler Master 700W GS Series +Tri Led
Cooling Fan
Sapphire HD6970 Graphics Card
DVD Writer
Logitech Cordless K/B & Mouse
Anything I could change? I think the GPU is ATI? I'm more of a NVIDIA guy

, so should that change?
I haven't added an SSD as I'm still 50/50 on it.
Lastly, what do you estimate I'm looking at for this computer?
Because everyone else here didn't give you anything with concrete longevity, I'll post up what I'll be recommending in my NAG columns later next month. I'm not guaranteeing that you won't be upgrading - rather, you'll be adding as time goes by. I'll explain what exactly you'll be adding later, just have a look.
Intel Core i7 3770K (Ivy Bridge) @ R3343
GIGABYTE Z77X-UD3H @ R1916
Mushkin 16GB DDR3-1333 kit @ R861
GIGABYTE GTX670 2GB DDR5 @ R4672
ADATA SX900 64GB (Sandforce) @ R1161
Western Digital Green 2TB @ R1228
Sony BWU-500S @ R1317
Corsair HX650 @ R1317
Corsair Carbide 500R @ R1064
Microsoft Windows 7 Home Premium 64-bit @ R1077
LG IPS235V-BN (Yes kids, that's an IPS panel) @ R2036
Total: R19,992
Okay, so its not as extravagantly kitted out with hard drives like yours but you'd be insane to buy multiple drives now, the damn things are too expensive. Likewise someone here suggested SLI and that's too extravagant because we have the GTX680 and GTDX670 showing everyone that you really don't need two GTX560Ti cards anymore. For now, at least.
A few things you need to take away here; first, I've listed the best Ivy Bridge gamer's chip money can buy. Its a quad-core with eight threads, so as games start to take advantage of Hyper-threading and virtual processors that badboy will earn its keep even five years from now. Do not buy any aftermarket air coolers because the ones available don't cool Ivy Bridge chips down any more than the stock one does. Watercooling units will fare much better, but the thermals of the chip are different to Sandy Bridge and it won't overclock as high for now. Wait until there's a revision of one the major cooling designers until you make your move. For now, 4.2Ghz on stock voltages will be possible with temps hitting about 85 degrees.
Secondly, high-speed RAM isn't going to help many people today unless they're tuning their system and running benchmarks. DDR3-1333 is still very fast and I've chosen Mushkin RAM over the other kits. With a little latency tightening, it'll run better than most kits out there anyway. The board I chose because it has enough expansion possibilities including multiple PCI slots for legacy cards like TV tuners.
The GTX670 runs in exactly the same performance bracket as the GTX680 with about 5% performance difference in most games. Given the card's lower TDP and temps, it will overclock much higher and bring you more rewards. Later you can nab another one on a sale and SLI them (do this in about a year or so). A single one will last you two years, SLI will go up to four so long as you scale down settings when you reach that point.
I also included a Blu-Ray drive because in the future you're going to want to make Blu-Ray rips of your movies and store them onto a NAS or a shared folder. As notebooks begin skinning themselves to anorexic levels and DVD drives disappear, you'll be glad to have your movies in high-quality MKV rips. Watching a high-def anime rip on a tablet is also something to experience.
Also yeah, that's an IPS panel. You'll struggle to find anything with the same kind of colour quality and intensity on other TN panels. I know I've left you with no spare change, but I'm sure you can stump up another R300 or so for your Logitech wireless bundle.
Everyone else: PCI-E 3.0 is nothing but a marketing gimmick at this point. Z77 offers native USB 3.0 support with Ivy Bridge chips, so that should be your reason, not some silly high-end connection standard that no-one intends on fully utilising anyway.
