Upgrading from a 5770

[Kalrax]

I'm thinking about upgrading from my 5770, which is starting to fall behind. I'm hoping to spend as little as possible (~100) - should I grab another 5770 and crossfire two together, or should I just go out and get a new card instead? If so, which?

CPU-wise, I've got an i7-920.

Thanks in advance for your help.

Well based on my knowledge i would get either a GTX 650 or a 7770.

I will quote from Don's monthly GPU review :

"....I don’t recommend upgrading your graphics card unless the replacement card is at least three tiers higher. Otherwise, the upgrade is somewhat parallel and you may not notice a worthwhile difference in performance....."

with this in mind, I would said 7850,660,7870,660Ti card are the good route...
but it somewhat out of budget range so...

my oppinion is to hold out with 5770 and save some money...
when new gen 8xxx, or 7xx card out the price will drop and the budget has increased (from saving)..
