Hello everyone, this is my first time posting on this forum and I would just like some help. So as Christmas is coming up, I was planning on asking for a more capable GPU to run more demanding games (cough AC UNITY cough) and for a higher frame rate.
So here the main specs so you could see if it's even possible etc:
Case
CORSAIR 230T COMPACT GAMING CASE - RED LED + SIDE WINDOW
Processor (CPU)
AMD FX-6300 Six Core CPU (3.50GHz/8MB CACHE/AM3+)
Motherboard
Gigabyte 970A-DS3P AM3+ (ATX, DDR3, USB 3.0, 6Gb/s)
Memory (RAM)
8GB KINGSTON HYPER-X FURY DUAL-DDR3 1600MHz (1 x 8GB)
Graphics Card
2GB AMD RADEON™ R7 265 - DVI, HDMI, DP- DX® 11, Eyefinity 2.0 Capable
Power Supply
CORSAIR 550W VS SERIES™ VS-550 POWER SUPPLY
Processor Cooling
Super Quiet 22dBA Triple Copper Heatpipe AMD CPU Cooler

So my question to all of you is, What would be the best move to make for an upgrade? A AMD or Nvidia? Best one in price range (MAX=£150)
-But then could I run 2 amd's together is it worth it? or just to get a good nvidia card?
As I have no clue if I could run my single gpu with another one, or if it's better to get a different gpu all together.
Thanks!

Or for the same price, or less, you can get any number of GTX 760s:

http://www.amazon.co.uk/Nvidia-DDR5-PCI-E-Graphics-Card/dp/B00DQ4GYFW/ref=sr_1_3?ie=UTF8&qid=1414814050&sr=8-3&keywords=gtx+760

Since you're looking at dual card setups, SLI will be more consistent than Crossfire. Crossfire is still plagued by frame pacing problems on DirectX 9 and OpenGL games, and in general isn't as well supported with drivers as Nvidia SLI. Add in the fact, that you can take advantage of PhysX, TXAA, FXAA, HBAO+, DSR, etc. With the price the same, you'll get better consistency and more options for better graphics...

Thanks for the response, yeah I think the r9 280 seems the best and it fits in with my model but then it annoys me when games seem to more optimised to Nvidia than AMD. Do you think I could sell my current r7 265 and then get the r9 280? As it seems annoying buying a gpu that costs £130 when the current one cost me value wise around £100, as essentially the totalprice would be £230. But then, in terms of performance, that's a bargain.

That's not a 280x. That is a overclocked r9 280. The model name from VTX3D is the X-edition.

I would sell the r7 265 and use that money to help pay for the r9 280 if I were you. The 280 is quite a bit faster and has very good performance at full hd(1080p/1920x1080): =on&prod[6788]=on]http://www.tomshardware.com/charts/2014-vga-charts/compare,3593.html?prod[6935]=on&prod[6788]=on

Ok after looking it, it seems like a great price for performance at only £130 however just before adding it to my list, I saw that it required at least a 700w psu while mines a 500w, some people said that's only if you had it in crossfire, so I am confused at that, and furthermore with my current specs would it fit in and be able to connect right?

That's actually a decent deal; I'd personally go for it.

Now having put that out there, for just a little bit more, have you considered a single GTX 970?

After reviewing this all, that actually doesn't sound like a bad idea, as opting for a GTX 970 obviously would be a bit more pricey (£240?) it means I'm set for a while and I think the switch to Nvidia would be beneficial as well. I looked up the power required and I think it was around 174w, given my current spec, would I be able to install and run this GPU on my rig?

I am pretty sure you could run it on a 550W power supply but I personally think it would be the bare minimum.

Here is Guru3D's power supply recommendation:

GeForce GTX 970 or 980 - On your average system the card requires you to have a 500 Watt power supply unit.
GeForce GTX 970 or 980 in 2-way SLI - On your average system the cards require you to have an 800 Watt power supply unit as minimum.
If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.
