1366x768---5850???

[fatfatr]

To start off, I have a 32" 720p LCD lying around so I'll probably game on it once I buy a VGA cable. This is most likely a stupid thing to ask after reading other threads on this topic but, would I expect a nice enough performance boost to justify paying $130 more to get a 5850 over a 5770 at 720p? I have enough money for a 5850 and I prefer going this route, so I won't have to crossfire the 5770 later on for desired performance.

I'll wait till the 5830 comes out but, that's irrelevent with the point of this thread.
I read the article on building a balanced gaming PC, I found that the performance difference isn't much different than at 1680x1050. That was comparing a 260 GTX to a 4870 x2 though so it doesn't really help much. Is going a bit overkill for future-proofing a stupid idea?

I would like some opinions on this to help me decide. ( I'll be using a Phenom II x4 955 )

Between the 5770 and 5850 at that resolution you wont see much of a difference but the size of your wallet. Now once you switch to the 32 inch, that could be another story as you could run it in a much higher resolution i imagine. so the 5850 would be a better choice then.

Yeah, I read a few threads stating that the 5850 is pointless considering the price difference over a 5770 at 768p. But after reading this article, I'm not sure. I mean it sounds stupid but, from one side I guess a 5850 wouldn't be that bad. I just need someone to clear this up.

I suppose it depends on what you play. What do the benchmarks show for your game(s) at that resolution? Truhls, I read it that the 32 inch IS the 720p one.
FWIW, I just got a new 1920x1080 monitor, and was worried my HD4850 would be weak. My primary game is Guild Wars though, which isn't very demanding, so even in Lion's Arch (which is crowded), FPS was still pegged at 60. I have all settings maxed except no AA; might turn that on just to see what happens...
I really don't want to "have" to get a HD5xxx until ATi fixes the flickering, grey lines crash bug.

An HD5770 should be great for that resolution for a long time. Forget about the HD5850, even an HD5830 will be almost totally pointless.

They did, a while ago. Basing your purchases on an issue suffered by a small minority is a mistake in general any way.

Oh hell, the 5770 would be sufficient enough for running games maxed out at my resolution. I was just worried about running new DX11 games coming out maxed out/ without AA. I guess time will tell. Now that I think about it more, the 5850 wouldn't be necessary as I won't really be future-proofed with either option.

Thank you for the replies.

All you need to do is get an HD5770 and a motherboard that is crossfire capable. Add another when you deem it necessary. Two HD5770s in crossfire give performance similar to an HD5870.

Oh yeah, make sure the second PCIe slot is at least x8.
