650vs7770vs550vs560vs6850

Title says it all .
Ok so i have like £120 maximum to spend on a new graphics card and I was wondering what do you recomend? and should I sell my 450 to fund a 560?
Also are there any good retailers in the uk asides from Ebuyer?
I have heard some bad reviews about overclockers uk

The cards you mentioned are all good cards, and from the fastest to the slowest are:

- GTX 560 (faster)
- HD 6850
- GTX 650
- HD 7770
- GTX 550 Ti (slower)

The GTS 450 overclocked well reach the GTX 460's performance.

The GTX 550 Ti is a bit faster than the GTS 450, but you probably wouldn't see any performance boost in your pc.

The GTX 560 is a good card, and you can find it at £130.

The HD 6850 is a good GPU too, it is slower than the GTX 560 but beats the GTS 450. You can find it at £120 or less.

The GTX 650 and the HD 7770 are similar for performance, and they are good cards if you don't use extreme resolutions. You can find both two at £85-£95...

And, if your motherboard supports it, you can consider to add a second GTS 450 and make a 2-way SLI. Graphics performance increase will be about 90%. GTS 450 costs no more than £75 now...

If you sell your GTS 450, you can consider to buy with your money an HD 7850 or an HD 7870, which are very nice cards.

If only my motherboard did support sli :/

if your motherboard didn't support it, and if you want to sell your GTS 450, then go for the GTX 560 or the HD 7850/7870...

What will you do with your pc? Ultra graphics gaming/ultra resolution gaming/HD video editing/3D modeling...?

Mainly gaming but im considering not getting a new graphics card and buying a new mobo

if you change motherboard, keep sure that your CPU, RAM, Hard Drives, PSU, other PCI/PCIe cards which are currently installed in your motherboard are compatible with the new one...

I'm not sure it will be a good choice... Changing motherboard will be a waste of money i think... the Amd Phenom X4 840 is a good CPU for gaming, and with a GTX 560 or better with a HD 7850 or higher (not a lot because a high end GPU would be bottlenecked by your CPU) your pc should be a fine gaming machine...

So, in my opinion, you can choose between two options: upgrade your GPU if you need it or save money and buy a new pc... Changing motherboard will be a waste of money if you keep your old hardware...

Ill take your word for it then but i noticed that most 560 TI's are around 660 priceing are we talking aabout a non ti 560?

i was talking about GTX 560 non-Ti.

GTX 560 Ti is a little faster than non-Ti version... But GTX 660 is better than both GTX 560 Ti/non-Ti
