HD7850 possible bottlenecks?

yes that processor will bottleneck it, 4gb ram is sufficient for gaming

I think that processor indeeds bottlenecks an HD 7850. Of course you need sufficient amount of power supply. 4GB RAM is sufficient (for gaming yep).

Thank-you for the replies.
would a 500w or 460w psu be enough? There's only one slot. I was looking also at a 430w 80+ corsair. Does modular/non modular make a difference? my board only overclock the gpu,and I don't think I'll need to @1080p.

Also,
would downgrading to a hd7770 still give maximum 1080p performance?
sorry for posting twice.

430w should be enough for an i3 and a 7850.
Modular power supplies are often easier to use and less efficient than their non-modular counterparts (usually)

with graphics settings set to medium at worse if you wanna hit that 60fps sweet spot @1080p

i recommend the 6870, 560, 560ti, or 6950 if you're looking for something cheaper than the 7850, but better than the 7770

Thanks for the quick response
Then if I'm not mistaken,core i3 2120 + HD7850 will Max everything at 1080p? This will require a 430w psu.
Will stock cooling work? I can't overclock anyway,just wondering how hot it could get.

not the best of temperatures, but stock cooling is fine if you don't overclock. you can always get another heatsink much later

You will hit at least 30 fps on almost anything on 1080p but on highest detail settings on most modern games you won't quite hit 60 fps. And if you aren't overclocking the stock cooling is more than sufficient.

how terrible is gaming at < 60fps? I'm really trying to avoid any lag and distortion of quality. My budget is limited but I'd rather stretch it. Would a factory OC card help?

With v-sync on you should barely be able to tell the difference. I'm a firm believer in MSI's efforts.

Would a Msi twin frozr 3 work? Its the one available to me.

Thanks again.

Looks great to me!

I believe he may mean <60 fps because the 7850 will likely not get over 60 fps in most modern games (all maxed) as stated above. Anything above 30 fps is considered playable as long as 30 fps is the minimum frame. If 30 is your average you will run into problems in high particle scenes with fps lag. If you meant >60 fps than refer to the comment quoted above.

Edited. I hadn't noticed.
I think I'm okay with an avarage higher than 30fps if the gaming is smooth. Can't hope for too much on a budget.
You guys are great.
Thank-you

based on this, at 1080p, with an i3-2120, you're only going to be facing with a few demanding games performing close to 30fps or less, like metro 2033 and Just Cause 2 at max settings, though that's most likely due to your GPU than your CPU. with a 7850 instead of a 6950, you're looking at some minor improvement though at worse.
