Here are the parts I found that could deliver to Ireland via amazon.uk. Sadly some of the parts they didn't have(the windforce 980) so I just picked what they had in stock. Others they were not allowed to ship to ireland for whatever reason.....Not sure on the budget for whatever reason this in in pounds.

If you have a microcenter in your area you can get a free mobo with processor purchase most months, depending on sales. Since I buy computer parts frequently here's a build I would make at $400:

8core processor/mobo bundle: $120

This gpu should be twice as fast: $110

This pc will require a 500w psu: $32

G.Skill 8gb ram: $57

Here's a faster, twice as large HDD: $55

Don't forget an optical drive: $40

Derp forgot a case: $17

All in all around $450
