Monitor Resolution: 1920x1080, may upgrade to 1920x1200 and use the old monitor as a secondary screen.
Additional Comments: Would like a quiet PC, for this reason have a preference towards Silverstone Fortress FT02. Also require an SSD for boot/games, and a secondard HDD for storage. Also would like for the mobo to lend itself well to upgrades in the next year or two.
I had the following as a rough first draft:
Silverstone Fortress FT02B: £179.98
HD 6970 2GB : £257.63
i5-2500K : £166.98
2TB Western Digital Caviar Green : £119.04
120GB OCZ Vertex 3 : £151.34
ASRock Z68 Extreme7 Gen3 : £228.82
8GB Corsair Vengeance 1600 : £36.19
Total : £1240.46
I am in the US and I must say you guys have some high prices there due to all the taxes.
First thing is your motherboard...get Extreme 4 and don't worry about gen 3 it adds nothing for GPU. Anandtech.com tested it on the new 7970 and it does nothing for gaming. MOtherboards are one area where the features seem very nice..but when you think about what you need the lower end boards perform the same as high end. So get Extreme 4..another thing..get p67 instead of Z68 since you have an SSD anyway. If you need intel quick sync then get Z68 Extreme 4 if not the p67 Extreme 4 has some great deals..atleast in the US.
You ram...this is another area people go for the fancy...get the cheapest DDr 3 1600Mhz 8gb kit..with cas latency 9 or 8...all ram perform the same...and overclocking doesn't do much for gaming.
Your case is pretty expensive..I wouldn't pay $180 dollars..forget pounds. BUt thats your choice..My recommendation is to get a CM 690 II or Cougar Evolution for under 70 pounds...and then buy silent fans..I'm sure it will still cost less than 100pounds and your purpose will be solved..these cases can fit any graphic card and have all the stuff you might need.
So basically take that extra 150 pounds you saved and try to get yourself a Radeon 7950 on Jan 9th...or even a 7970 depending on UK prices.
