Crossfire my 5770 or go for a 6950

post #1 of 40
Thread Starter 
So yeah, If I get another 5770 I wont have to buy a new case because it would fit, only buy a new PSU. That would be around 120 e for the card and 70 e for the PSU.

Or should I get a 6950 and sell my 5770, get a new case and a psu.. Is it worth it?

CF 5770s are a bit faster than a 5850. And the 6950 is quite a lot faster than a 5850. Definately the 6950. A 1GB can be had for around £195 which is nice.

hd6950 does worth the extra cost,its even faster than hd5870,
for the pc case u can get Antec 600 $75 at newegg or Antec 900 $90 at newegg,for the psu get corsair tx750 for $80 from newegg,with tx750 u can run 2x hd6950 cross fire,
hope this helps u

5870 is about 3%-5% faster than 5770 CF. 6950 is about 3% faster than 5870. Used 5770 is pretty cheap here (I don't know whether you can get one in your place), it is a good upgrade if you can get one. On other hand, the extra vram in 6950 does help in high resolution. 5770 is around 110w and 6950 is 200w so not much different if you go either way. If you want to keep the rig for a while, probably sell 5770 and get 6950, down road get another for 6950 CF.

6950 without a doubt, it will be significantly more powerful than 2x5770s and will come without the hassle of crossfire (driver issues, game compatibility issues).

best solution is get a 6950 and then unlock it to a 6970. They you will get an even more pronounced performance increase over cs 5770s. Its the best deal on the market right now.

Alright, I'm getting the Antec 600 case. Would Corsair 500w be enough for the GPU? AMD site says 500w should be enough.

I'm getting the 2gb version of the 6950, but would VGA be any good brand? I've never heard of them, so I dont quite trust them, but they're considerably cheaper than the next 2gb model(around 20 euros).

A6950 is about 11% faster than a 5850. Which isn't even noticeable. How does that translate to "quite a lot faster?"

Only if you are running at resolutions high enough to take advantage of a 2GB video buffer. Otherwise, a 1GB 5870 performs the same and costs WAY less right now.

The 6950 and 5870 exchange blows, with about an equal number of wins in each pocket across the wide spectrum of possible tests. The variance is within a few percent in either direction in most cases.

Wow... Someone actually looked up some numbers before responding. Give this guy a pat on the back!!!

Significantly more powerful?
A 5770 is basically half of a 5870 (half the cores, half the memory bandwidth, etc), which as I explained previously, performs on par with a 6950. The only edge a single 6950 has on a set of CF5770s is scaling losses, which aren't that bad in the places that count. CF5770s are routinely considered on performance par with a GTX470, which the 6950 is intended to compete with.

6970 is only about 10% faster than a 6950. Why does everyone seem to think that 10% difference is enough to even notice? Even worse....Making that 10% out to be a "big deal."

"Even more pronounced?" The 6950 would not even be noticeably faster than the CF5770s to begin with (in many cases it would not even be any faster), bumping it to a 6970 might just barely be enough to make the difference almost noticeable on rare occasions. In truth... probably only if you play with the FPS counter always displayed.

Devilmaypoop,

I'm sorry your thread has been filled with so much misinformation. I hope that in the future, people will do their homework before responding "from the hip" with their gut feelings about model numbers that sound big and fancy doing the aiming.

Preparing your rig for CF5870s (proper PSU and room) now would be the best route. The PSU and case will last for many years if you get decent stuff, so this investment won't be wasted. Then, when you can afford a 5870, snag one. At that point, sell the 5770. That will ~double current performance. Then when you can afford another 5870, snag it and double the performance again. That will translate to a total performance increase of roughly 3-4X from the current single 5770. It can be performed in logical steps, and you won't be dumping money into overpriced new "model numbers,"

By the time you get around to buying the 5870, who knows, maybe the comparable 69XX series will have come down in price enough to justify...

Eric

Somewhy every internet shop around here sells the 5870 about 50 - 100 euros more than a 2gb 6950, so yeah.. It's kind of strange. And the 6870 wich should be alot cheaper than a 6950 costs only about 10 euros less.

+rep anyways for a good post.
