Haven't built a PC in years but am strongly considering building one again for Crysis, Counter Strike, Company of heroes and a whole host of other games. My budget is around 800 euro without a monitor. This is the spec I've selected so far, Radeon HD 4870 1GB GDDR5, PCI-Express 2.0, DVI/HDMI/DisplayPort, Antec Sonata III Miditower, Black w/500W PSU, Intel Core 2 Quad Q6600 2.4GHz, MSI P45 NEO-F, P45, Socket-775, DDR2, Corsair TWIN2X 6400C5DHX DDR2, 2048MB (another 2gigs), Western Digital Caviar SE16 500GB SATA2 16MB 7200RPM. All this comes to just over 850. Is this a good spec or is there anything better you'd recommend.
