I saw an AD in Fry's this weekend showing that I could get the HD5770 for $169 USD.

I've actually been very, very pleased with the performance of my HD4770. The biggest difference, other than DX10 vs DX11, is that the HD5770 boasts some nice speed improvements over my current card.

I don't spend $300 on any graphics cards these days but this price is very enticing.

the 5770 is the best card you can get for the buck.
its a nobrainer if you ask me.

its kicks 4870 ass with ease.

Just give it some more time and they will drop the price even further.

Looks like a good buy to me http://www.gpureview.com/show_cards....=612&card2=615

The extra gpu ram should help.

But we don’t have that luxury with the Radeon HD 5700 series. The value of the 5770 in particular is clearly not going to be in its performance. Compared to AMD’s 4870, it loses well more than it wins, and if we throw out Far Cry 2, it’s around 10% slower overall. It also spends most of its time losing to NVIDIA’s GTX 260, which unfortunately the 4870 didn’t have so much trouble with. AMD clearly has put themselves in to a hole with memory bandwidth, and the 5770 doesn’t have enough of it to reach the performance it needs to be at.

If you value solely performance in today’s games, we can’t recommend the 5770. Either the 4870 1GB or the GTX 260 would be the better buy.

"But don’t mistake that for a wholesale write-off of the 5770. As a 40nm product it’s cooler running and quieter than a 4870 or a GTX 260. As a DirectX 11 product it has longer legs to run on for future games and/or applications using DirectCompute 5.0. Eyefinity is also there, but with the performance of the card, (not to mention the cost of more monitors) it’s not something we’d seriously expect to see used on a 5770.

Our jobs would be made much easier if AMD had either made the 5770 perform at parity with the 4870, or made the 5770 cheaper. Right now on a good deal we can swing a 4870 for $140, while the 5770 will be sticking to $160. That’s 14% more for a card that performs 10% worse. If we take a linear extrapolation, the 5770 needs to be at around $130 to win on performance alone, or at the very least $140 so that we can talk solely about the 10% performance loss versus the extra functionality of the 5770."


If you play in resolutions above 1680x1050, indeed the HD 5770 is an upgrade from the HD 4770, but if you don't, it would be barely an upgrade. If only performance matters to you, then buy the HD 4870 which is between 5% and 15% faster overall and cheaper, but if DX11 is a must, then get the HD 5770 since the DX11 path will push the card on HD 4870 performance territory and beyond.

I appreciate the feedback on this.

But, I did specify that the upgrade [for me] is from HD4770 to HD5770. And, as stated above, I've been very happy with how well my HD4770 has performed with the games I play. So, if there's a significant improvement in performance AND since it's a DX11 card, the price is attractive to me.

I would not be interested at all in going from one HD4xxx card to another HD4xxx card.

But like I stated previously, that depends if DX11 matters to you more than performance, HD 5770 its only an upgrade if you play above 1680x1050, otherwise, its like moving from a HD 4770 to a HD 4870 512MB plus DX11 support, which isn't bad, but not that great either, if you expect a lot, you will be dissapointed, better go off to a HD 5850 if its possible, but if your expectatives aren't that high and you want 30% or more performance plus DX11, just go for it, if you enjoy your current card, for sure you will enjoy the new card.

Seeing as I tend to upgrade my video card about every 9 months to a year, the HD5770 is appealing to me for what it's worth.

I think next spring, if things don't completely go down the toilet economy-wise, I'll likely do a full system upgrade.

If the PSU holds up, I don't plan on doing anything with it. But, like HDDs, and most other things, PSUs are made to fail. This one is already over 2 years old.
