I'm looking to move out of the world of laptops and buy/build my first PC in a few weeks time. However I'm also utterly clueless when it comes to PCs & components so I've got a few questions. I'll start with the build I'm currently thinking of going with (hoping to use it to game on my ASUS VH242H at 1920 x 1080 for the next 3 years or so), it's essentially the enhanced PC from the topic with a few changes for components I can't get on Overclockers:
ZOTAC GeForce GTX 560Ti "448 Edition" OC 1280MB GDDR5 PCI-Express Graphics Card £199.99
Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail £169.99
Asus P8Z68-V LX Intel Z68 (Socket 1155) DDR3 Motherboard £89.98
Cooler Master HAF 912 Case - Black £52.99
Seagate Barracuda 7200.12 500GB SATA 6Gb/s 16MB Cache - OEM (ST500DM002) £57.98
XFX Pro 550W Core Edition '80 Plus Bronze' Power Supply £52.99
Corsair Vengeance Blue Low Profile 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CML8GX3M2A1600C9B) £43.99
Cooler Master Hyper 212 Evo CPU Cooler (Socket Intel® Socket LGA1366/1156/1155/775/AMD Socket FM1/AM3+/AM3/AM2+/AM2) £26.99
Samsung SH-S222BB/BEBE 22x DVD±RW SATA ReWriter (Black) - OEM £18.98
Arctic Silver 5 Thermal Compound (3.5g) £8.99
Total: Around £740 with shipping.
Assuming there's nothing horribly wrong with the build my first question is would I be better off spending £30 more or so on the GPU to get a GTX 570 from here
http://www.overclockers.co.uk/productlist.php?groupid=701&catid=1914&subid=1010 or the AMD equivalent?
Second question would be a matter of RAM. So I need to go with the Corsair Vengeance LP or would I be able/better off to go with the standard version given my GPU cooler & mobo, I know some guys on Overclockers were worried about the heatsinks on the standard version getting in the way.
Finally there's the matter of cooling. I was thinking about replacing the stock HAF front fan with a 200mm Megaflow and then using the stock 120mm fan to rig a pull/push setup on my 212 evo. Would that be possible and should it be sufficient enough to cool my machine if I go for a 4.2-4.5 OC on the CPU?
Anyway those are all my concerns to now, many thanks to anybody who takes the time to read this.
