here a list for UK
ps its under 1000gbp - so you can consider taking "your" case - but it would be better to invest in the R5 1600X // ps you are more likely to replace the GPU in 2 years - so better invest in the stronger CPU
You are so worried about FPS because the internet tells you that you need to be. Never mind that unless you have a 144 hz monitor most of the frames above 60 are wasted. Yes Yes before everyone jumps on me I am aware that the higher the frames it often correlates to a smoother experience. That usually applies to having some head room not necessarily double plus what the monitor can display. This is a stock clock MSI Gaming X RX480 8gb on Ultra settings in Dirt Rally from just a few minutes before this post. I didn't realize toggling to my other display while the benchmark was running would freak it out and freeze it at 15 fps so the average probably would be in the mid 90's as it took me a minute to catch it. Intel is not the end all be all to gaming. Neither is Nvidia. Do they make good products? Absolutely. Are they worth the premium you pay for them? Only if you get it in your head that they are! Budget building should be about spending wisely not spending more than you need to because the internet is divided. Also you are on an AMD forum, what did you expect to be told here?
I wasnt sure if you had an OS to use already but given you are using a PC I figured you did. Here is the build I would most likely use if I had to stick to a 1000 pound budget. https://uk.pcpartpicker.com/list/VYBff8
