I have an alienware m17x r2 with two ATI mobility radeon HD 4870 graphics cards (1gb each)
One of the two cards comes up in device manager as device cannot start (code 10) even though the latest drivers are installed (many years old, this is dellienware specific, i can't just go to ATI and download the latest)
anyway, i'm sure one of the two cards is bad, so i want to upgrade both.
currently, just scrolling pages like msn.com, scrolling is so choppy it takes 1-2 seconds for the screen to even catch up. sometimes just typing is delayed. even with nothing else running, virus scan clear, hitman pro clear, malwarebytes clear - basic video runs like garbage
i've taken the machine apart completely, blew out dust, cleared fans, re-applied new thermal paste, it still runs like garbage. one of the two cards has to be bad
the current driver installed for each card is:
so my question for points here is - what are my upgrade options for video cards? i'd like the budget to be under $200 or so but i need to know for sure it'll work (the cards will fit, will be functional in crossover/sli/paired mode, and drivers will be recent/update able)
so what do you guys think?
