It seems that you're better off going with an HD 6870 for roughly the same price.

Thanks for the info guys, Looking at the 7850 it has a core speed of 860 compared to the 7770's core speed of 1000, Why is that, Shouldn't the one with the higher core speed perform better?

To be honest I can't afford the difference anyway. It's about 50 quid more (UK) I'm pushing what I can spend as it is by going for the 7770. I'm planning on building a new pc at some point as I'm stuck with a motherboard max of 4gb ram currently but that's probally not gonna be for about a year now. I'm delaying at the moment to see if AMD improve there processor range as the fx stuff does not sound like it lived up to the expectations. Intel seem to have the best ones currently. The price is the issue with there kit though.

I was about to get 7770 too, but from reviews i see that people say that is better to get 6850 wich is better and cheaper, since i dont know much about comps , shouldn't bigger number mean better, like 7xxx is better than 6xxx series?

I misread Grunt's post and looked at a 7850 instead of a 6870.
I currently have the 6770 Part of why I am going for a 7 series is it uses newer architecture. To be honest I don't fully understand what that entails apart from it requires less power to run. But I went from a 5770 to a 6770 and found out they were identical which was a gutter where as this 7 series version is quite different. It is also important (I think) to get the correct 7770. There is a version with 2 gb ddr5 and 2 fans aswell as the model with 1 gb of ddr5 and 1 fan. So far it is the cheapest 2gb dual fan model I have found. I will have a look at a 6870 but really I want to go for the newer 7 series.

Well, the HD 6870 may have lower clocks but, it has more shaders, ROPs, transistors, and bigger memory bus width.

But it seems that the massive overclock to 1 Ghz helps the HD 7770 keep up with the HD 6850 in terms of performance. It's not a bad card at all.

And unless you're running 1080p and/or dual (Or more) monitors, another extra GB of VRAM won't help.

Comparison of cards' specs at the bottom:
http://www.techpowerup.com/reviews/AMD/HD_7770/1.html

Power consumption chart:
http://www.techpowerup.com/reviews/AMD/HD_7770/24.html

I had a Zotac GTX 560 Ti 1GB with 1 fan (Performance between HD 6870 and HD 6950, I exchanged it for a Gigabyte Windforce x2 GTX 560 Ti OC), and it never went over 70 C under 100% load.

As you can see from the power consumption chart, it uses half the power my GTX 560 Ti needs under average and full load. So I'm sure 1 fan will be able to hold the line.

It's temperatures:

http://tpucdn.com/reviews/AMD/HD_7770/images/temp.gif

The "+ OC" one is when they pushed it to 1.145 Ghz from 1 Ghz and memory clock to 1.495 Ghz from 1.125 Ghz.

So are the 560's better in your opinion? I've only had AMD models apart from my first card which was a 9800gt or something like that. I've gone 5570, 5770 and 6770. I just saw this 560 which is likely to perform better in your opinion?

Well the GTX 560 Ti is better than the HD 6850 and HD 7770 but the 'normal' GTX 560 isn't.

I would say go for either an HD 6850 or HD 7770 1Ghz since you're more familiar with AMD cards/drivers.

EDIT: I would go with the HD 7770 1 Ghz because of the lower temps and power consumption. Both are at the same performance level anyways.

Thankyou

Thanks for the advice I went for the 7770. I chose the 2gb though. Skint me out for a while due to the new processor I got last week. I would of liked the ti but couldn't afford it, maybe the equivalent model next time. Next I want a better Hard drive as mine only shows as 5.9 on the Windows Experience Index. Every other section is at 7.3 till the new card comes. I'd like to increase my 4gb of ram but that will mean a new motherboard so it will have to wait till next year. I'm gonna build my first pc from scratch then. Thankyou for the help Grunt, boredgunner, R K Roadkill, Kobold, burger and The walking ghost.
I appreciate it.

I cancelled and ordered this. It is the better one isn't it? There seems to be loads of versions of it

Yeah, that's a pretty good card to upgrade to.

For hard drive... Maybe get a small SSD for OS + favorite games? Most open world games constantly stream textures from the HDD/SSD as it constantly loads areas.

Then just keep the hard drive for the other stuff.

Next year when you get a full-blown upgrade... Maybe consider Intel's upcoming Haswell chips. It's a "tick" on Intel's "tick tock" system which means it's a good time to upgrade there.

Tick = Sandy Bridge *i3/5/7 2xxx*. (Decent/Large performance increase over older gen)
Tock = Ivy Bridge *i3/5/7 3xxx*. (Small performance increase over older gen)
