Hi all, new to the forum but there doesn't seem a better place to be asking this.

I'm contemplating upgrading my 6670 to a 7850 2gb as the benefits obviously speak for themselves, but I'm wondering whether to crossfire my A10-8500k with the 6670 instead? Is the performance of those two components comparable to a single 7850? And are there any negative effects to the APU when it's crossfired and not running as a standalone CPU?

Thanks in advance for any input.

I say try the CrossFire since you already have the components. Makes sense to try out what you already have? Right?

Crossfiring with 2 6670's will of course be the most cost effective, just be careful as both crossfired 6670's and the 7850 are recommended having at least a 500W PSU by AMD.

From a performance standpoint a singe 7850 would be significantly faster than the 6670 in CF.

Since you already have the parts try it out. 7850 is way better though.

I do not have any CF experience, but I will say my rig in my specs. runs BF 3 and Far Cry 3 on Ultra settings, with no visible issues to my eyes. Of course my 19" monitor supports 1280x1024 so I know that has something to do with it. I can say the 2G 7850 is a excellent card at it's price point.

Thanks for the input guys. I'll give the CrossFire a go, if it affects the CPU performance too much I'll just knock it straight back off. I think I will go for the 7850 in the long run, I just wish I'd have added that to my build first time round instead of the 6670. Mind you, I should have gone for a Sabertooth motherboard and AMD FX processor as well, it's my first new PC for six years and I sort of dived in mand built it then did my homework later.

The PSU is a good point, I have read in some places that the 450W will handle the 7850 (around 220W under load) whereas others have suggested a 600W would be needed. I'll do a little bit more research on the PSU side before buying the 7850.

Thanks again for the input.

450W PSU is plenty for the 7850. Peak consumption is around 100W. On the other hand APUs are meant for cheap "good enough" low/medium settings gaming experience.

Yeah I think I'll just hang on then and get the 7850. I can't believe I'm upgrading my PC just a week after getting it through, I really should have been more patient in the spec process.

Apus are meant to be used as they are for low end gaming, crossfired apu+6670 would give you 7750-7770 at best so dont waste your money on that get a 7850/gtx 660 or better.

I didnt realise AMD released a 8500k. Joking aside, its not that bad of a quad core processor, but a 7850 would be way better than your current gpu. the 6670 uses DDR3 vram right? you'd get instant gains from merely going to GDDR5 memory anyway. Would make for a decent midrange rig in honesty.

My mind's been made up, I'll get the 7850 in a couple of weeks.

The site where I built my PC offers an upgrade from what I have to the 2GB AMD Radeon HD7850 at about 10% cheaper than anywhere else, but I had been looking at the Sapphire. This time I'll be doing a bit of research before just jumping in and buying.

I think I may go for this ASUS HD7850-DC2T-2GD5.

Yep, I've decided to go with the ASUS 2GB AMD 7850 975MHz model. I like ASUS gear and the card looks good at the price point (£165/$245).
