This build would do awesome gaming.
+ i5 3350p is just little less powerful than the 3570k. Just clocked a bit lower and without iGPU. Awesome for gaming.
+ 7970 is a very good GPU. Infact the R9-280X is just a rebranded 7970.
+ 8GB RAM is ideal for gaming. 1TB HDD should be more than enough for everyday needs.
+ NZXT Tempest 210 is a great case with nice cooling ability and for a good price.
+ Antec's 650W 80+ Platinum PSU is seriously a no compromise PSU. Very high quality and quiet.
+ Windows 8.1, you may replace it with Windows 7 if you prefer so. I prefer Windows 8.1
+ Asus' good 23" monitor with 2ms response time, smooth for gaming.
