Here's an interesting point of thought - I just trolled through a bunch of reviews and it looks to me like the 4670 has a fairly quiet ace up it's sleeve. I specifically was looking for CrossFire reviews with the 4670, and for those that have a CrossFire capable board and are on a budget (buy a card now, save up, buy another later) you're in for a treat. In almost all of the tests, 2x 4670's not only smashed the 9800GT, but either was within a couple percent or faster than a 4850.
This of course doesn't come without it's caveats - as now you're looking at a multi-GPU setup, and have to deal with some of the issues with CrossFire. But here's a couple thoughts:
- Assuming you have a CrossFire capable board (which I would guess most with Intel CPU's do these days), this is a pretty huge value to you.
- Pay around $70 for a decent low-to-mid range card... get decent performance.
- Save up your pennies and wait for a good deal on a second 4670, and have even better performance on par with higher-end parts (4850).
The catch is that prices will always go down on these things, so why not wait until you can snag a 4850 or even a 4870? Well, for starters, if you're on a more budget box, odds are you have a lower end PSU. The 4670 doesn't require much in terms of juice!
Again, it's all up to the buyer, but the 4670 is a really REALLY nice card.
