Strange Video Output w/ Memory Dump

If it's doing that even during before windows even starts at all then it's definitely hardware trouble of some kind.

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.

Edit:
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!


Edit:
Er, just gonna make a new topic then.
Will assign a best answer.

Here's the thing, the HD 5830 is only about the same raw performance wise as what you have now. So to get something better you'd have to get an HD 5850 or 5870.
