Some people will say MSI some Asus some EVGA some Gigabyte some something else! Main thing is get it from a respectable manufacturer with good warranty. I personally would choose between the 3 first manufacturers I listed and purchase based on price.
There isn't much price difference between the MSI, ASUS, Gigabyte 770's but the RRP for the ASUS is over £400 does this matter or do they all perform the same ?
@pyr0_m4n - what resolution do you play on while using the 780 ? as I am only going to be playing games on a 221inch 1920x1080p monitor so would a 2gb 770 be enough and future proof ?
