hello all,

well, as you've probably noticed, i need to choose which graphics card to buy. Clearly the 6850 is much better and more efficient that the 5770, but i want to know how much i really need for gaming. Once i get the video card, I plan on playing games like mw3 and Assasin's revelations on high settings. So tell me, is it really necessary to spend an extra 70$ on a card that in which there is a chance that there will be no noticeable performance difference?

also, the 6850 is pci-e 2.1, and 5770 is pci-e 2.0. so will i be able to stick in the 6850 card into a motherboard which only supports pci-e 2.0?
 
currently, the (reference) radeon hd 6850 is the most powerful gfx card that requires only one pcie power connector. for gaming, it is more capable than 5770 (see dm186's at comparison link).
pcie 2.1 is a minor update over 2.0, it is completely compatible with pcie 2.0 (which is almost all motherboard pcie 2.0 slot).
end performance depends on the rest of your specs. you should be able to play the listed games at high settings as long as the rest of your pc balances out the gfx card.

resolution 1900x1200 hp 27" led

i want to play games on 'good' settings, something that will make me realize that i wasn't just building this new rig for nothing. I currently have an 8yo pc with a very olddddd video card. benchmarks lower than radeon 4200HD. so something that will get me a good deal on what i'm looking for. i'm not the type of gamer that will see a difference between 5 fps or between dx 10 an 11






not relevant to thread: the hp debranded monitor i was talking about was on newegg for 250$ couple of days ago. the deal says its deactivated. do you think that the deal will come back? because i cant find an hp 27" debranded led monitor on any other site, they all link to newegg.

you are getting a 5770 and 6850 at 80 and 120 dollers respectivly :eek:, these prices are mindblowing.
its not a deal, its a steal
i got my hd6770 for 140 dollers,

you can maxout mw3 with a 5770 with 75fps or more, but i dunno about Assasin's revelations.
At these prices you should grab that 6850

Yeah, go with the 6850 or two 5770s in CrossFire. At ~1080p a single 5770 isn't enough (but for MW3 it will).

I see that mobo doesn't support cross fire though, so i guess go with 6850. You'll be able to max out MW and maybe assassin's creed too. Good for future proofing too.

The point of a better GPU is that you can crank up the visual detail at higher resolutions without sacrificing frame rates.

Deactivated stuff may not be back at all, don't wait on it...

but does anyone here actually have experience with powercolor? i looked at the reviews and such, and it says that their only problem is that they often times screw up the rebates. so there is a chance that i might have to pay 150$ instead of 120.


and rmpumper, i understand that the benchmarks are much better on the 6850, but do you actually see the difference?
