Sup,

Approximate Purchase Date: Next few days

Preferred Website(s) for Parts: Any UK retailer
Country: UK

Notes: DVD/CD-R Drive required. I feel pretty set on a i5-3570k. Must boast a 1TB HDD at least. At least 8GB RAM. Don't have a clue on GPU's so suggestions are welcome. Would enjoy some strange audio outputs on the rig, SP/DIF? Everything else is subjective.

I'm really not too bothered with SLI/Crossfire capabilities, although it would be a welcome bonus. Overclocking is a must. I'm a tad unsure about the GPU mind

All suggestion welcome. I want to get this perfect since it's a lot of money to ah heck it up.

i'd advise to get 7870.
other than that looks good.

If overclocking is a must, what CPU cooler are you using? The intel stock cooler will not cut it for anything more than the mildest overclock.

Thank for your replies. Gone a tad over budget but this seems like the ticket.

I will buy a CPU cooler when i'm ready to OC, I must learn first. A few questions; many companies offer the same GPU type (7970 ect) although prices can fluctuate in their £30's, what is the difference between these?

Also, I have a compatibility warning and wondered how I could solve this 'ASRock Z77 Extreme4 ATX LGA1155 Motherboard has an onboard USB 3.0 header, but the Zalman Z9 Plus ATX Mid Tower Case does not have front panel USB 3.0 ports.' ?
