Ive used PCS twice before and havent had any issue with them. but I will shop around for a few comparable quotes, I tend to use them to benchmark the price and specs tbh., because their quoting tools are quite good.
I have built my own rigs in the past, so may do so when it comes to the crunch. as its a big cost saving and I can shop around for parts and get the cheapest prices., plus no build cost other than sweat, bad language and a weekend of my time to put it all together.
I could add a bigger box to allow a couple of additional 120mm fans, I did have my concerns also about overheating. but tbh, i probably wouldnt overclock, firstly I dont know how, and secondly I dont know how. lol
the difference in price between the RTX3080 Ti and the next level up, 12Gb is over £500 so thats going to put the 12Gb out of my price range. im already exceeding budget by £500, but thats an acceptable cost and I would take that on the chin. we are alrwady in 'lies to the missus' terrirtory.
Wont be buying just yet anyway, as I still have furniture to buy, so it will depend on whats left over, but I have massively over budgetted for that anyway. so there should be a few shekyls left for a new rig.
