Potential new build, thoughts and help

[fronomore]

Hi I have decided to build a brand new PC as mine is pretty old now so I really need a complete overhaul. I already have windows 7 OS so won't be needing that and I also have a keyboard, monitor, mouse and speakers. Here is my proposed build which I will be playing games such as Guild Wars 2, Shogun Total War 2, Skyrim etc on:

1x Intel Core i5 3570K 3.4GHz Socket 1155 6MB Cache Retail - £177,
1x EVGA GeForce GTX 560 Ti 2GB GPU - £204
1x Asus P8Z77-V LX Socket 1155 VGA DVI HDMI 8 Channel Audio ATX Motherboard - £90
1x Western Digital Caviar Black 7200RPM SATA 1TB HDD - £80
1x OCZ TECHNOLOGY 600W 80plus MODXSTREAM PRO OCZ600MXSP ATX12V & EPS12V PSU - £56
1x corsair 8gb(2x4GB) ddr3 1600mhz xms3 RAM - £40.00
1x LiteOn iHAS124 SATA DVD Optical Drive - £16
1x Coolermaster HAF 912 Plus Case - £66.14
Total Cost=£729

Just need views on the build, whether those components are the best for their price range or whether I could save some money on any of them without sacrificing too much performance, This would be the top end of my budget so I would not be able to go very far above it.

Thanks for such a quick reply, as for reusable drives I could probably salvage the Optical drive off my old PC, as for the HDD it will definitely need replacing. The build you have proposed looks good but not sure the storage on the SSD would be enough? I have a lot of music etc. Budget wise I could probably stretch to about £750 but that would be the top end, however I would be comfortable spending that much. Also the PSU i suggested was 600w not 800w?

Oh and I have Windows 7 Retail

Yeah the Optical drive is definitely sata, thanks very much for the suggestions. Will having the SSD speed it up much then? I guess I'd just put the OS and maybe my most played game on it then use the HDD for everything else?
