Hello I am building a high end (budget limit around 1300 eur) PC gaming rig , 100% custom job and assembly process by me. No more pesky private handlers As usual time to get with the parts is huge when building custom PCs I understand that and I am well experienced with tricks in this market. But sure , who doesn't want to spare a few bucks , even if you could get the costlier stuff with no prob. Facts like this , if not using Dual-core GPU , no more than 1 HDD etc , the need for an over 650Watt PSU is obsolete , even 550 would be enough theoretically , right? I am used to this custom builds , planning takes time , since HD5870 is a month away and planning to buy the parts around min november when COD6MW2 comes out. Also note that I do not have any access to a global credit card , and parent surely wont trust in the online purchasing (but we have other ways purchasing online here; that means ebay and amazon and anything that uses paypal only is not a choice) Since AMD stood up , fixed TLB bug , and an excelent second edition of Phenom , there is no way I can resist this , so AMD Phenom II X4 965/955 definitely. It is yet not final if 965 really has anything worth 40 bucks more except a 200MHZ increase , so 955 is more likely, just for 180 eur. Next what is definitely it's Gigabyte GA-MA790FXT-UD5P , the top one there is. Personally I don't like Asus mobos(high failure rate reportedly?) , but other things are good , bad thing is , company can't specialize in something cause they make a ton of different things. But still I haven received no info when there will be a new AMD mobo being as good as Intel one , Intel has UD6 this is an upgraded UD5. If the new one comes out lower than 200 price I'll definitely take that one. The RAM would be , don't be surprised , Corsair Dominator DDR3 Dual Channel 2x2GB 1600 cl8 PSU; It's not final but I think Enermax Modu82+ 625W(EMD625AWT) will be enough and quite quality powerfull (Revolution has great new features but quite expensive at 850W which is the lowest version) I hope it supports cross rail system, so the 3 rail separate won't affect the PC power requirements. GPU: One and only , Radeon HD 5870. (ATI Cypress?) HDD: Already got that, WD Caviar Black 6400AALS (32mb) Case: Coolermaster Cosmos S, yes it's extended ATX , supports all three ATXes, fun thing was I planned this one before I knew how long the GPU will actually be so this case is just aligned with that in mind , it will never fit into ATX case, HD4870 fits but with the PCIEpower cables connected it is really tight. Main thinkg why I want eATX is you have more space which is quite important as it may seem not. CPU Cooler: Coolermaster V8 Also I am thinking of buying several system fans , just I don't know about these so much , which brand is ok , and with blue LEDs make nice look too. That's it , any recommendations , anything to add? Also I will assemble the whole PC my self , I have knowledge but never done that in practice, what's the key things to be careful of other than electrostatic and thermal paste splash?
