4870 1gb vs 4870 512 vs 4850 512 CF

Here is what I'm seeing:
4870 1gb $300
4870 512 $220
4850 512 $120

i guess even w/a 512 memory, 4850 512 CF is performs better than a single 4870 1gb even at 1900x120 & costs $60 less

honestly go for something with 1gb of memory. 512mb is starting to show its limits. I have a 4870x2, and Farcry 2 at 1680x1050 with 4xAA 16xAF(Ultra High) eats up to 750-910mb of VRAM. Crysis also ate upwards to 900mb of Vram on the final boss (same settings)

For crysis you can just use the integrated benchmark tool, it just runs while you play or you can do the Crysis Tool, and just run scripted benchmarks, it shows how much ram is occupied.

no it doesn't show the amount of vram... it shows the amount of phsysical ram being used... warhead rarely goes over 1000 while the original crysis can eat up to 1400

so its not vram...

wow 100$ keyboard ftl

How's about 2 1gig 4850's ? You seem to want an ati product. Those cards at that res should be fine.

dear death look at post times

the time i opened thread was before 7:08 so i didn't see your post... + g15 is an overly expensive keyboard


you fail dumbass

I'd say that neither of you 2 are productive right now. So I think both of you should tuck in ur e-penises and help the OP

P.S

Whats wrong with a 100$ keyboard? I have razer Tarantula paid 90$ + tax. What's the problem?


@ Op

try to get a 1gig car dif your going to go for the 4850s

I see more than a couple misconceptions about ATI cards and memory. Unlike Nvidia where they use wider buses to fully support more memory i.e. 8800GTX with 384bit bus that can address a full 768kb of memory, or 280 with a 512 bit bus that can address a full 1gb ATI still is using a less expensive 256 bit bus on the 4000 series cards. So your 1mb card really can only address 512kb. They doubled the memory and used it along with some addressing scheme that allows them to improve throughput but the 4000's can still only address 512 at a time which nullifies the argument about more memory for larger textures. Since they don't share memory the 4870X2 still has 512kb addressable per card.

its not actually far, its about 5 fps, but you notice a difference Plus the 1 gig has a higher min frame rate

Its a hit miss, obviously the 1 gig is either as good or better than the 512. People tend to forget that the higher the Vram the higher the min frame rate, not good enough to have avg with a good min.
