So my laptop recently died due to an Act of Kitten (like an Act of God - uncontrollable, chaotic, and impossible to hold a grudge over although sadly not covered by insurance). This was fine because I'd been meaning to replace it anyway, and it is the latest in a succession of sucky cheap laptops - but, although I absolutely love my job, it does not exactly pay out the mega bucks and I'm left trying to find a new PC for under £600 (I'm in the UK, FWIW).
I looked at the Puppy & Dolphin builds on the front page and according to amazon.co.uk, the cost of the Puppy set-up with the Dolphin memory & graphics cards will run me up to about £575 (which is juuuust about affordable within 2 months' paychecks for me). That's just the components, though - I also need speakers, an operating system, a keyboard, and a wireless card because my landlord absolutely refuses to drill holes in his walls for me to run cables through for a wired connection (which is, you know, fair enough).
My local computer shop is selling a pre-built machine with 8 GB of RAM, a 1TB HD and an "Intel G2120 3.1GHz Dual Core CPU". I have literally no idea whether or not that's better than the AMD FX-6300 from the Puppy build. It's also listed as having "Intel HD Graphics" but there doesn't seem to be a detailed component list on the handout they've given me. The machine is £349 for me because it's a family-owned shop & the owner owes me a few favours, and includes a copy of windows. I could buy this PC this month without needing to split paychecks to afford it (I am ok with eating ramen this month). I believe that if I bought this machine this month, I could buy a better graphics card next month, should the current one not be up to snuff (the shop owner is off sick but I'm going in to see him next week to get a list of components).
Should I stick with the Puppy components or go for the cheaper local option? If I go with a cheaper local option, how terrible IS an unspecified Intel HD graphics card likely to be compared to a Radeon or an NVidia? What kind of components should I be on the lookout for that will run WoW at decent-ish graphics? My benchmark for 'decentish graphics' here is 'can play melee in a 25-man raid with the graphics settings at 'Fair' without becoming a slide show' which would be a novel experience after the nightmare that is my succession of sucky cheap laptops (once, I got 20 FPS in the middle of nowhere... it was a great day). I'd like to play on Good or Ultra settings but I know that's going to cost more than I can afford, so any advice for a broke wow-player would be gratefully appreciated.
TL;DR: I suck at tech, please help.
