So, where exactly do you fix the TP-LINK TL-WDN4800 in the computer case? To the graphics card or somewhere else on the motherboard? And I'm buying another 8gb ram module, so thats better than 2 4gb ones.
YES, The CXM 750W is a little overkill for that a CX500 will b enough CX 600 if SLI A SSD would boost performance. Get this Rams, as 2 modules will enable dual channel more performance http://www.amazon.co.uk/Corsair-CMZ8GX3M2A1600C9B-1600M...
This little cheaper http://www.overclock.co.uk/product/Corsair-8GB-DDR3-PC3...
TP-LINK TL-WDN4800 is compatible with Asus P8Z77-M as long you USE A slim single slot GFX Card NOT the 660ti
YOU CAN NOT USE TL-WDN4800 WHEN THE 660TI card INSTALLED (GTX660TI is DUAL SLOT CARD) DUE TO LIMITATION OF SPACE BETWEEN SLOTS.
Get the PCI one instead Get TP-Link TL-WN951N install it in the last blue slot on the motherboard.
Yes as long you use 2 memory modules in 2 slots fine.
EDIT: You can use a usb WIFI adapter instead for internet connection. ( SO no need change GFX Card )
