ATI 5770 worth a try?

[jeffyd123]

I recently got a 5770 Radeon and was looking at the specs of it and my 4890 that Im currently using.... the memory and GPU speeds are very similar.

 

Im wondering if there would be a worthwhile performance gain by switching cards... otherwise Ill sell the 5770 and save up for a NVidia card (im thinking of trying 3D out)

 

thanks for your input

4890 is faster than the 5770 or atleast on par.

So you should sell it. The 5770 is too slow for dx11 anyway and only advantages over 4890 is lower power consumption and possibly not as noisy.

I can't speak to the comparison of the 4890 but I own a 5770 1g ATI and things run really well for me. If I were you though, and the 4890 is playable, maybe save up and get a Nvidia 560ti I've heard really good things about that card.

 

P.S. What's your CPU?

Too slow for dx11? Every DX11 game i have runs fine.

I have 2 5770's, however I found using just 1 works much better in this sim. I'm able to use all high settings, msaa 4x, hdr on, 1920x1200 and get constant 50+ fps in most situations.

 

I have quite a few newish games that I get very good fps with very high settings:

 

Aliens vs Predator

Batman: Arkham Aslyum

Bioshock 1 & 2

Dead Space 1 & 2

Mass Effect 2

Metro 2033

Chronicles of Riddick

Fallout: New Vegas

Last time i compared specs I think the 4870 series that I have has a much larger memory bandwidth.

my resolution 1920 x 1080

 

5770..76.8 gb ps

4870 115.0 gbps memory bandwidth

OK thanks everyone.... I think I will try it out and report back if there is any difference.
