Today, the 4890cf will outperform the 5870 in dx10, but not by a large margin. In time the 5870 will grow in its abilities, if the 4xxx driver arch is to be trusted as any sort of precedent. I think the 5870 would be a safer investment in the long term, especially with a CF option open as the prices drop.
Best solution

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.

My Phenom's not bottlenecking?I thought it was since i get 30fps average in Crysis Warhead but a website said it had over 40 fps average (1920 X 1200 4x aa)It might be but the review probably had a monster CPU oveclocked to get that 40 fps average. But you said you'll get an i5 soon too.

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.0Those pictures are engineering samples and do not reflect what the final product will look like. It will get a PCB and cooler shrink. The name seems to be a point of confusion right now. Some are calling it the HD 5970 while others are calling it the HD 5870x2.

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?

ok and do know any retailers that currently has 5870s in stock?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.i dont get you and as long as you have a motherboard with a pci express x16 or somthin like that it should work
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
