Upgrading from 4830 to 4870? and new build?

Hey, I want to know if I should upgrade from a 4830 to a 4870

I have $600 to spend on a new PC (just the tower, not monitor mouse keyboard and operating system)


I already have a 4830 video card, and wanting to know if I should upgrade it to a 4870

the prices of the two are

$90 4830 from newegg

$165 4870 from newegg

I was thinking maybe I could sell the 4830 for $50 so I want lose so much money.

and also, if you guys could suggest a new build for me that would be awesome! (off newegg.com please)

also, would I see a big performance in crease on crysis? I use the 1600 by 1200 resolution.
I used to get 20-30 fps in crysis on everything at LOW at 1024 by 756 with my 4830 (4gb ram, 2.7 ghz 7750 kuma)

thanks!!!

No, keep the 4830, Crossfire it with a second 4830. You don't need to scrap a perfectly good card just to get a 4870. With 2 4830 cards you should be playing Crysis on high, no problem. It seems to me these cards preform better with AA,AF on anyways. Though I know it maybe harder to find 4830's now though, seeing as AMD stopped making them. Lots of people on here can offer you a good "new" build, if that's what your after. Though, if you have an X2 7750, you should be ok. Hope that helps.

......... One of the posters above "the card being perfectly good", and these little cards are. Unfortunately Crysis looks like crap at low res. and I'm sure it still spits and sputters some.

I bought an Asus 4830 for my nephew a few month's ago. It played everything pretty good at 1024x768........his resolution. At 16x10 it played COD4 pretty darn good on my computer. Crysis on the other hand tanked. If your card is the 512 variety I'm not sure Xfiring it will be too beneficial for Crysis. I own a 4870/512 card. Still not good enough for Crysis @ 16x10. Perhaps a 1gig card might or one of those new 4890's ( YES ) would do the job. I run a single GTX260 OC and it runs that game fine @ 16x10........these are getting cheap now.... check newegg. I think Saphire has a 4870 with 2gig of memory on it. Though the 2gigs don't do a whole heck of a lot, from what I read the couple of extra FPS at those higher resolutions might just help games like crysis playable.

If you recycle your hard drive that would save a little money too.
