Advice - 4870 Vs 5750 / 5770

Hi all,

I was originally tempted to wait for the ATI 5850's to come down in price a bit. However, I feel a bit desperate for an upgrade as my 8800GT only has 256MB onboard, and is suffering in GTA4 as a result. Its a shame because otherwise its a decent card, just lacking memory.

So I've been looking at cards around the £100 mark, and there's these 2:

Sapphire ATI Radeon HD 5750 1GB

Gigabyte ATI Radeon HD 4870 1GB

Edit: Well we could factor in a 5770 for an extra £20 if its worth it:
Sapphire ATI Radeon HD 5770 1GB

I like to play at 1080p resolution.

From what I've seen the 4870 is faster? but the 5750 has DirectX11 and I did read something about better image quality, if thats true?

Any advice?

5770 is a better comparison to the 4870 really.

ok, just added on the:

http://www.overclockers.co.uk/showproduct.php?prodid=GX-216-SP&groupid=701&catid=56&subcat=1515

If its worth the extra 20 bones.

Direct x 11 hits performance a bit also.

So i would imagine playing latest games in direct 11 on 5750 would be poor....

Well, whether its true, they try to sell DirectX 11 that it will be help improve performance....

 

[markiejt]

going of benchmarks for only direct x game it hit performance

Buy one 5770 - then buy another one and make CrossFire

ok, been reading various peoples opinions around forums, and reviews and people are quiet split.

However, I am edging to a 5770, because it performs about the same as a 4870, uses much less power/heat, DirectX11 and has better video acceleration. I've read about the technical features of DirectX11 and it sounds impressive, also with hope that drivers will improve further in the future.

Not only this, from here:

In the future, if I need more brute power Crossfiring them gives impressive results, matching the 5850 and sometimes bettering the 5870!

go for 5770, better than other 2 choices.
