Hey guys, this is my first thread, and well its basicly that, will my HD 7770 bottleneck my intel G640 (2.8GHZ) and how could i play BF3 on 1360x768 resolution (19'' monitor),
ive seen a video that shows a dude playing BF3 on ultra settings having the exactly same PC settings as mine only that with a 6670, that is quite inferior
actually im playing with the shitty intel HD graphics 2000, lowest settings, 800x640 and i get around 15 to 25 fps, tottally depressing :( LOL..

here's my full pc specs

intel g640
4gb ram
Ati 7770 (to come)
PSU 600w
HDD 500GB

I ran BF4 with a Pentium G840 tied with a GTX 260 and 4GB RAM; I was unfortunately not able to get steady frames, and the game often froze. However your experience may vary, as you do have a GPU with DX11 support; the DX11 support with BF4 actually reduces CPU load (source), whereas my GTX 260 supports up to DX10.

Regardless I believe it's primarily down to the processor, and it will bottleneck your GPU. I have upgraded my Pentium processor to the Xeon E3-1230v2 (4 cores and 8 threads, similar to the i7-3770) and I was able to play BF4 at high-ultra with constant 30 FPS. BF4 will utilise additional cores and Hyper Threading; hence even an i3 will provide better FPS on BF4 over the Pentium.

Unfortunately with that said, I don't...

First, never believe everything you see on You Tube. Second, gfx cards don't actually bottleneck CPUs. But your Pentium dual core could be bottlenecking the gfx card. What is the problem you are having at 720p and at what settings?

Hey I'm also using the same processor right now...my GPU is HD 7770.i cant even play BF4 and BF3 at 60fps in ultra.when i checked my cpu performance graph,the readings shown were above 95 percent....this cpu bottlenecks any of the gpu in AMD 7000 series as well as Nvidia equivalent.

so try to save money and go for an i3...I bet you will not regret like me.....

Unfortunately with that said, I don't think the Pentium will cut it and will bottleneck your GPU; apologies to be the bearer of bad news. An i3 or better should handle BF4 at a decent frame rate.

All the best. :)
