I wanted to get some of your opinions on which choice I should make. I've done a little bit of research and it seems HD5770 crossfire about equals, if not is slightly better than one GTX 550 ti. Maybe I'm wrong, help me out lol. Since the HD 5770 is so outdated I can only get an HD6770 to crossfire it with (Yes, you can do that.) I'm leaning towards going back to Nvidia though, it's been a while. Are there any better options for me? I don't wanna spend over $150. Any help is appreciated. Thanks.

My Specs
Windows 7 64 bit
ASUS M4A785TD-V EVO Motherboard
AMD Athlon II x4 620 @ 2.6 (3.1 OC) <-- Future bottleneck?
8 GB RAM DDR3
XFX Ati Radeon 5770
700 watt PSU

What!??!? Where did you read that? Single GTX 550 Ti is around the same speed as SINGLE HD 5770. Crossfire would be way faster.

For $150, that'd be a hard thing to beat as far as maximum framerate. But if you're looking for more consistent framerates (i.e. from a single card) you might just want to get a 6850 or a 560 non-ti. You might be able to pick up a 6870 used for $150.

One of the reasons I'm trying not to crossfire my 5770 is because it's an old card. I'd rather have a single card anyways and crossfire it in the long run. I think I'm gonna gonna go with a 6850 then buy another one in a few weeks. Thanks guys. And @Flying Toilet; what CPU do you recommend I upgrade to?

I would suggest the 960T, it's a pretty versatile chip and usually has some good overclocking headroom. You will need a pretty decent overclock to crossfire in the future. The 970 at the Egg is sitting at $109 right now though, and most people can get that over 4 Ghz pretty easily. If it's still that price when you're ready to xfire, I'd go with that.

You can post a classified here I think, not sure what the minimum requirement is. Other forums will allow you to sell once you meet a certain requirement. Otherwise, Ebay would be a good place to start for a more secure transaction but you might not get as much as you would on the forums.

5770 cfx will perform close to gtx 570 or higher, with a lot of microstuttering. it will perform higher than a gtx 550ti.
your cpu is a possible bottleneck for 5770 cfx even with overclock. if you wanna upgrade, aim for a phenom ii x4 965 b.e. or higher and overclock it.
for your rig, a single powerful card is a better bet. i'd recommend a radeon hd 6870. it's 'close' to $150 (actually $170~) and better performing than a 5770 or 550ti. nvidia's 6870 equivalent is a gtx 560 non ti. imo currently 6870s are of better value.
if possible, i'd recommend a complete pc switch to an intel core i5 based one for better gaming experience in the future (unless amd comes out with a better gaming cpu with piledriver).

Okay. So, either crossfire PLUS get a better CPU which will cost around $270 (too much), but will perform the best, do a complete pc swap for intel (which I'll do, but in the near future), or go with a 6850, or 6870. I'm still undecided. I'm doing constant google searches. I just want 60 FPS at 1680 x 1050 with high settings. No multi-display or anything crazy. Looks like I'm gonna wait a little bit and settle with a 6870. Still not sure yet. You guys are awesome by the way. Thanks for all the feedback!

er.. i meant to say that - skip crossfiring 5770 cards entirely. higher theoretical performance does not always mean better gaming experience. that's especially true for entry level cards. crossfiring entry level cards don't make sense because of their weaker gpus usually cause microstuttering - if you're susceptible to it, it'll be problematic. if you wanna crossfire amd cards, look to radeon 6950/7850 and higher and latest amd catalyst drivers... and at least core i5 2500k.

if you live near a microcenter, check out these (i am not asking you to get it, just notice the price):
http://www.microcenter.com/single_product_results.phtml?product_id=0354589
http://www.microcenter.com/single_product_results.phtml?product_id=0388577
only problem is, these are in-store pickups.
the 6870 card looks good. make sure it fits into the case.

i'm not sure about the 1045t, the base clockrate looks too low. if you oc it, then no problem i guess. if this saves you a year, you can go for haswell later. :p

Stay away from 6 core CPU's for gaming. It hasn't been until recently that a majority of games utilized quad core processors, and up until that high clocked dual cores reigned supreme. A higher-clocked quad will certainly beat a lower clocked hex-core at least 90% of the time, if not all the time for gaming.

Thanks for the advice Flying Toilet. I'll avoid the 6 core cpu's. Now, back to the crossfiring with my current CPU. Are you POSITIVE there will be micro stuttering, even with an OC? I'm only asking this because I stumbled across this today http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2451&CatId=4928
It's basically the same setup I have except the motherboard has 2 x16 slots instead of 1 x16 and 1 x8 slots. I was told that wouldn't make a difference with 5000 series. What do you guys think?

Not Sure if im too late to the party but ive benched my own system recently
I run crosshair v formula
sapphire hd5770 in crossfire (x2) @ 930core 1300mem
Amd fx 6100 6 core @4.5ghz all cores active
8gb ddr3 1866 memory
xfx xxx series 650wpsu
my results show my system perfoming at gtx570 lvls graphically
i have 0 microstutter in my games and i used this review for comparison
http://www.tomshardware.com/review [...] 196-4.html
i only post this to you cause i found those results interesting as i was looking for some hd 7870 info as thats my next card
im going to get for crossfire
later hope these shed some light i read this post and couldnt believe soem of what i was hearing
about 5770 crossfire. ive been running it for 2yrs now as the mb and processor seemed like the better upgrade from athlon 2 640 (and it was ) people who arnt running 5770 crossfire in dual 2.016x slots underestimate its gaming greatly.
hope this helps if you havnt made a purchase yet

1 thing i forgot was i was running my crossfire on the mb you have m4a785tdv-evo in 16x2.0/4x2.0 and while it performed well enough to see scaling i got a huge improvement on them going to the crosshair v with its 16x2.0 slots So yeah hope im helping if im not late already lol
