Hey chaps last time i bought a pc was 2013 a little worried about building my own I came here and was so happy with the advice i was given ive come back.. 6years and my computer:

1 x Intel Core i5-3570K 3.40GHz (Ivybridge) Socket LGA1155 Processor (77W) - Retail £167.99
1 x HIS HD 7850 IceQ X 2048MB GDDR5 PCI-Express Graphics Card (H785QN2G2M) £155.99
1 x Iiyama ProLite E2208HDS 22" Widescreen LCD Monitor£99.95
1 x Asus P8Z77-V LX2 Intel Z77 (Socket 1155) DDR3 Motherboard £69.98
1 x Corsair Carbide 200R Compact ATX Case - Black £49.99

1 x OcUK 24x DVD±RW SATA ReWriter (Black) - OEM £15.98 Total : £727.85 (includes shipping : £12.50). Plus mouse headset harddrive keyboard and win7pro

And i can play vermintide 2 with graphics up to high. But time for a change, not bought an xbox1 or ps4 so that £400 toward the budget plus red dead, black ops 4, fallout 76.. might even sell my old spec only if theres nothing in it i could use.. if possible can someone spec me for £700 budget, and looking at getting a decent monitor for around £300.. thoughts on current monitor appreciated and if that £300 extra budget could be better spent feel free... thanks in advance

Thanks for your response, I'm thinking a few years of future proofing if its another £1000 I kinda wanna know the games on the horizon will look great and play well so..*newb* theres a i7 for £199 at mo new from OCs is there a limit to what my psu and mobo can cope with? think I'll go with an nvidia option this time I'm not sure why I changed to Radeon for this computer.. I like the idea of going above 60fps and improving on my current monitor.. and the SSD is definately the way to go.. I either buy everything now or I pace it out over the next year or so. what are the movers and shakers regards these upgrades is there anything I really should get first to see a benefit (thinking SSD or monitor) and wait to see offers on other components?
