Thanks for the advice, guys!
I borrowed a friend's 5770 and things seemed to be fine, although I do realize it draws much
less power than a 4890, so i figure it could still be the card, or the PSU.
If I can get my hands on another 4890 I will, but most likely I will try to RMA my card first.
I will update this thread as they warrant.
So I'm fairly certain its my 4890. I'm thinking of getting a new card and giving this card to my brother for his birthday.
since he really badly needs a new card and because I recently got a bonus at work)
Therefore, I am asking for input from any and all on what card I should get based on the above system.
In terms of budget I have $600 maximum and would prefer ATI over Nvidia, though I am not adverse to being
convinced otherwise. These $600 are Canadian (cause I live in Canada) and will be purchased from a local store.
(This store's prices are better than newegg.ca and ncix, but you can use those as reference places)
Thanks again for the help!
Er, just gonna make a new topic then.
Will assign a best answer.
