Hi everyone... Well, i'm new to the forum despite reading TPU for quite some time, and saw that you guys are really nice to new folks with doubts about their builds (different from Brazilian forums). So i came here to ask a few things about a new build i'm about to do... System Specs: Corsair Graphite Series 600T White Edition Gigabyte GA-Z77X-UD5H WB WiFi Corsair Dominator Platinum 8GB 1866MHz Intel i7-3770K Corsair H100 2x MSI GTX670 Power Edition 2GB (even with that overvoltage problem, ) OR 2x Sapphire Dual-X HD7970 OCZ Vertex 4 256 GB SSD Seagate Barracuda 1TB 7200RPM 64MB Cache 3.5'' Corsair TX850 V2 PSU Windows 7 Home Premium SP1 64 bit Main use: Gaming (lots of it) - New 2560x1600 monitor arriving... want to play everything at max and overclock the cards (not much, tho). Few video editing (school projects, short films on 1080p). Mainly working with Sony Vegas, but i intend to use Adobe After Effects soon. Browsing (obviously)... So, my doubts are: 1)After Catalyst 12.11, should i get a HD7970 or a GTX670? The gaming experience will change a lot between those cards? In Brazil, the price difference is like $30. And i can't decide what to buy. 2) I'll be able to do a push/pull configuration with H100 and the 600T? Already heard about some Corsair cases that don't have enough space to do push/pull because the motherboard gets too close to the cooler. 3) The 1866MHz Dominator Platinum will run fine with my UD5H? I did not find any compatibility issues with those two. Thank you very much for taking your time to answer my n00b questions And if wasn't for all the reviews here on TPU and all the members discussions, i probably wouldn't know s**t about what i intend to buy.
