I'm fairly new to this so some feedback is always welcome. It's primarily intended for a good level of gaming and watching hd movies etc. but on a budget of around £900-950 (after VAT), so had to compromise here and there. This is what I came up with:
CPU: Intel Core i5 2500K overclocked @ 4.3Ghz CPU Cooler: Xigmatek HDT-S963 Operating System: Microsoft® Windows 7 Home Premium 64-bit Motherboard: Gigabyte Z68AP-D3 Memory:8GB Corsair 1600mhz Vengeance (2x 4GB) Hard Drives: Corsair 60GB Force3 SSD S-ATAIII 6.0Gb/s 2nd hard drive: 500GB S-ATAIII 6.0Gb/s Optical Drive: 22x DVD±RW DL S-ATA Graphics card: NVIDIA GeForce GTX 560 Ti 1GB Sound card: Creative Audigy SE 7.1 PCI Speakers: Logitech S220 Case: Corsair Carbide 500R White PSU: 700W Xigmatek
More aboutwhat build
700w is too much. You can get a 600w and be fine. You can look into Crucial M4. I think the Asrock Extreme3 Gen3 is a really good choice for the price because it also includes a 3.0x16 slot if you ever want to upgrade. The GTX 560ti 448 is really good if your budget can handle it.
A good 700W might cover two GTX 560 ti in SLI. However probably not that Xigmatek. I would look for a Corsair TX750 V2, or OCZ ZT series.
