what mobo is it mate? what RAM are you buying? Gskill Sniper and Corsair Dominator are really good!
I suggest using this website to do comparisons and read customer reviews!
Newegg.com - Computer Parts, PC Components, Laptop Computers, LED LCD TV, Digital Cameras and more!
also, DO NOT BUY an AMD card with Intel CPUs', Gtx 570 is the best card to go with the i5/i7's, I have done enough research lately to know!
the ASROCK board:
Newegg.com - ASRock Z68 PROFESSIONAL GEN3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
Graphics card:
Newegg.com - EVGA 012-P3-1570-AR GeForce GTX 570 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
if you are not going to be editing HD movies etc etc, you DO NOT Need the i7, the i5 2500k is all you will need for gaming for many years to come! save yourself the cash and put into GPU! you dont need the 2500k version either if you are not going to overclock! but for an extra couple of dollar/pounds etc its worth it in my opinion as you do have the Z68 boards which allow for overcloking!
do not buy INTEL boards themselves, they are ****! Asus P8Z68 Deluxe/Pro boards are fantastic!
the MSI Twin Frozr GTX570 DDR5 is a (overclocked edition) is a great card too!
DO not get AMD card with INTEL CPU!!!!
any other questions jsut pm me vlad
