is this a suitable GPU? http://www.amazon.co.uk/XFX-Radeon-GDDR3-Graphics-Card/dp/B00H5DJDL2/ref=sr_1_2?s=computers&ie=UTF8&qid=1449075111&sr=1-2&keywords=r7+250+low+profile It looks good and is literally my budget and it doesn't require a 6 pin connector and is low profile, would it be good, and can anyone tell me if its got any downsides, bad reviews and what PSU it requires, Thanks
