Made requests for different parts to their Cerberus model; an 850 500gb SSD, since an M.2 wasn't necessary for my needs/budget, and a premium version of an 1080 GPU. Price adjustments were reasonable and their engineer was friendly and quick to reply and offer advice. I found their choice of components to be good - especially regarding access to fully modular PSUs with a rating of gold or more. Contact was kept throughout the build process and was clear and easy to understand.
PC runs 4k Skyrim SE at 59 FPS in all reasonable areas [had to tweak game inis and access the control panel, and I installed NVidia inspector. FPS counter going wild was in-game thing not a fault of the machine] - and I'm looking forward to reinstalling Witcher 3. WoW performance is flawless, even in larger raids.
Got my free codes for Mafia III and GoW4 as well, the latter I wasn't expecting with the GPU choice I made so it was a fantastic thing to see. UKGC were also accomodating of me wanting to install my own ready-formatted SSD as storage, so I'm glad it didn't go to waste. Delivery was a breeze. Runs quiet which is brilliant as I'm noise sensitive. Thanks guys. Would shop again.
