Which card should I get?

[prestxn]

I'm building first computer and the last things I have to get are video card, and psu. I'm stuck between a radeon HD 7770 and 7850. Which should I get if I plan on playing 1366x768 for about a year.

Asus M5A97 AM3+ motherboard

Fx-4100 Quad Core 3.6GHz (3.8 Turbo)

G.Skill 2x4Gb 1600

7850 has 2GB vram and 1024 GCN shaders, while the 7770 has 1GB vram and 640 GCN shaders. Im pretty sure the 7850 will be a better choice in the long run.

Yeah I too think hd7850 will be able to handle all games for you for a year at the resolution you specified. If you go to a higher resolution screen then you will face a frame rate drop in your games.

The 7770 is plenty for that resolution, it can handle games at 1920x1080 on medium/some high settings. However the 7850 is a much much stronger card that will be much better in the long run, especially if you play on upgrading your monitor to a higher resolution.

For your resolution a 1GB HD7850 would do quite well. I don't think you'd be disappointed by the HD7770 either (although you might need to lower AA), so let your budget decide.
In either case, get a Seasonic[-built] PSU. A G360 would run either card, although with limited headroom with a HD7850. A Superflower-built unit like a Rosewill Capstone or Hive would also be decent. A good size range is 450W-550W, which would allow plenty of headroom, especially if you want to OC.
