[Solved] 5870 vs 4890 crossfire

I gonna upgrade as soon as i figure wich to buy.When i upgrade ill also be upgrading my cpu ,a phenom X3 720 to core i5.My phenom's bottleneking too abd

the best reason i want to upgrade is because i think ill go crazy listening to that thing again.Its like a tree blower XD.And i got an response in 2 min. lol

omg response in 2sec lol i dont no im not that much against crossfire as long as theres not much noise.Are there any sug. for that?

5870 all day, it'll be quieter and almost as powerful... not saying the 4890's in x fire are bad, but i think it's more logical to get the 5870.

+1 future drivers will increase performance up to 30%

Performance wise the HD 4890's will win over the HD 5770's. But you'll miss DX11 and eat up a lot more power.

Ok... I've been down this road. I had a 4870 and bought a second for Crossfire. This was a few weeks back. The top card got SO hot it overheated and crashed. It was hitting 102C. The bottom card only 80C. The top fan was running 100%, so you want to listen to fans running. Oh boy! I ended up selling both cards, taking a bit of a hit and buying a 5870. Let me tell you the 5870 is pretty quiet even at load. It idles in the low 40C and I don't think its gone over 72-73C in gaming yet.

PS... your Phenom isn't bottlenecking crap, just stick with it. Get the new cards and you will see a difference.

holy crap i found pictures of 5970 (ty masterasia) !!!!! i bet it'll cost $800 xD and what happen ed to 5870 x2? did they forget to release it o.0

Crysis is a BAD benchmark when comparing systems. You can have a HUGE difference in systems and only gain like 2 FPS. Besides, I am not going to get into the whole bottlenecking debate in this thread. Just remember, every PC has bottlenecks, they are EVERYWHERE. Your CPU waits on the L1 cache, which waits on the L2, then L3, Then RAM, then Hard Drive. You just try to reduce the bottlenecks a little. An OCed i7 is going to outperform the same setup on a Phenom X3 720. However, if you have an i7 with a 4870 and a Phenom x3 720 with a 5870... Guess who wins?

The Phenom II x3 are excellent processors, that outside of synthetic benchmarks, hold up very well in the CPU/GPU balancing act.

MORE than enough. A solid 550 or 600w would do the trick.

you guys have any estimates on when they will release the 5970/5870x2?

i cant find any retailers currently selling HD 5870s T.T

January it seems.

Nope. And none of them should at the moment. I know of a few instances where retailers bought a few cards from other retailers just to fill orders.

Demand is simply higher than ATi and TSCM anticipated and yields were below expectations.

However, nVidia fans pointing out the low yields and availability for HD 5000 series cards might want to consider how things look for nVidia given that TSCM will also provide them with their 40 nm chips.

Worse for nVidia is that ATi simply buys chips individually as they are produced but nVidia buys a whole wafer at a time. Meaning every piece ATi buys works while every piece nVidia buys might only have 10% working chips.

hey I just hooked up a 4890 to a old 32 bit Pentium 4 board. I should've checked compatibilty first because I don't have that motherboard anymore. I wrote a complete description of the situation on anouther thread if anyone would like to comment.

With an old P4 CPU, he probably had an AGP based motherboard.

I can't find any liturature on the board and I can't get tech support from gateway because its to old

I'm thinking the same thing I'm gonna have to troubleshoot all the components. I've got a 790FX-GD70 Sitting on the shelf waiting for the AMD 965 to come in the mail. I was hoping to use the old board for business purposes. Looks like I screwed myself trying to play with new toys... At least P4 boards are cheap
