Should I get a 6770 or 6850?

So I contemplating if I should get a 6770 or a 6850. I can get a 6770 for $77 and a 6850 for $130. I'm on a budget but I feel that a 6850 will be more useful in the long run if I decide to play newer games with higher graphics.

3 Questions:
1. Is a Gigabyte Radeon 6770 is a good quality graphics card? (also if Gigabyte is a trusted brand)
2. Will my PSU have enough power to power this?
3. Will I need additional fans to keep a 6770/6850 this card from overheating?

My build:
CPU: i3 2100
MOBO: Gigabyte GA-H61M-S2h
PSU: Antec 450W
HD: 500GB 3.5

The 6850 is going to be the more futureproof card, but neither are particularly powerful compared to current mid-high end cards.

1) Yes, Gigabyte is a trusted brand
2) Yes, Antec makes a good power supply and 450W is enough
3) As long as your case is resonably ventilated, you should be fine. What case do you have?

I have a NXZT Mid 210

the 6850/7770 would be the last amd gpu that requires 1 6 pin connector before the large gap to the next card using 1 6 pin being the 7850. I would think the 6850 is a good buy for the middle range guy thats on a budget. though on the case of it actually fitting in the case and getting enough ventilation will be dependent on that case

That case is probably fine for ventilation.

I don't understand your comment about the 1 6 pin connectors.

How will I know if my case is big enough?

$77 for a HD6770? great deal right there. yes the HD6850 is better than a HD6770, but is worth ~$60 more? I dont think so.

Alright, thanks for the input.

I'm leaning toward the 6770 now.

I agree, the 6770 for $77 is great, and the 6850 while better, doesn't seem to be worth $50 more especially if you're on a budget.

Edit: Do you have a link to the 6770?

what i should really ask is what resolution and game quality are you going to be playing at. and when i say 6 pin connectors, most modern gpus require a specific plug from your psu to connect to your gpu. the only exceptions are old gpus and the hd 7750

I think you should go with the $77 6770. If you haven't been playing computer games much or have been doing so without a graphics card, you will be very happy with what you can do with a 6770.

Your PSU will have no trouble powering even a 6870.

However, the 6870 is periodically on Newegg.com for $130. That frequently gets double the framerates of a 6770 and would actually be worth the money (note that the 6770 is just a relabeled 5770): http://www.anandtech.com/bench/Product/296?vs=290
The 6850 is roughly halfway between them.

There are more exceptions on the PCI-e 6-pin power connector, but it's mostly for low end cards like a GT 240.

Speaking of lowend, that 6770 you linked uses DDR3. That is unusual and terrible. The only reason it is that cheap is because it uses old slow memory. Any quality graphics card should be using GDDR5, as is the standard for a 6770: http://www.amd.com/us/products/desktop/graphics/ati-rad...

EDIT: Upon further inspection, you can see that it's a 6670, which has substantially worse performance, especially the DDR3 version. What 6850 were you looking at?

Maybe it's a typo though. If it is, then that's an excellent price for that card.


That's odd. On newegg it shows it at GDDR5. Could be a typo. Maybe 2 different cards?

some cards have gddr3 and gddr5 revisions of them, ofc the gddr3 is the much cheaper and weaker version.

In that link you posted.....it shows a picture of a 6670, but in the description it has 6770.

Seems like they put the wrong description with the product.

Some 6670's have DDR3 (most, I think), but no 6770's do. I corrected my comment with an "EDIT" a while ago, but it looks like I missed everyone's refresh timing.
May 2, 2012 6:39:46 AM

If you're buying from there make sure you're actually buying the 6770

Yeah super odd. Not getting that. Might just go with the better 6850 :]

Totally unrelated side not: What is your avatar gif from? That grey character looks oddly familiar.....maybe from a verryy old game?

It's from SkiFree, which shipped with Windows 95 and 3.1, I think. Someone asks that about once every couple months.

I personally strongly feel the 6870 is worth $20 over the 6850: http://www.anandtech.com/bench/Product/291?vs=290
The performance difference varies from 5% to 30%. But since the 6870 can be found for $130, I think it's well worth keeping an eye on slickdeals and getting on Newegg's email list until that happens.

OH YEAAHHH! OMG I'm gonna re-download that game for the nostalgia~!

Are you sure about the 5%-30% difference? According to this chart I only see a little jump but I'm not an expert or anything.

Probably will go with the 6850 just cause of the budget. Now for which brand...

Well the 6870 is periodically on sale on Newegg for $130. When I consider the 6850 is rarely lower than $120, it's hard for me to recommend it. Without the 6870 there, it's well worth it.

You might notice that the GTX 590 is also slower than the GTX 480 on that chart when really the performance difference is roughly 100% in the GTX 590's favor. The passmark charts are...not especially useful, but somewhat meaningful in the correct context. Here's some more meaningful reviews you can try to form your own opinion with:

If it's a matter of $10 for the 6850 over the 6870, I'm willing to spot you to dime bill.

Wow, thanks for all the help AND for the offer. Really kind of you. I'm sticking with the 6850 since I heard the 6870 is a little loud and it's jussst a bit overkill for my needs. Thanks again

FYI: The GTX 460 V2, which is about on par with the GTX 460 1GB, but based on the newer GTX 560 core is on sale for $100: http://slickdeals.net/f/4317082-MSI-GeForce-GTX-460-Ove...

It's a hair weaker than the 6850 though, but cheaper. Anyhow, the 6850 is still a solid purchase.
