There's previews of their performance.
And a G620 won't bottleneck a 7750, a 7750 > Trinity's IGP (We have performance figures of the IGP, it's less than a GT640)
Pricing won't be cheaper than current Llano, so you're looking at a little bit more, but gaming performance will be better.
If Trinity comes out at say 60 quid for the A10, do you really think I'd say get a G620? No, not a chance in hell, but it won't.
Apply some logic and common sense you can make a logical assumption which will likely be fact.
For the i3 3220? If an i3 2120 can relieve the bottleneck of a 7950 compared to a Phenom II X4, you can bet the i3 3220 won't bottleneck a GT670 much if at all.
I'm being defensive now Cat, because from my point of view, you're attacking me/questioning my stance, so I'm explaining.
EDIT : It's upto him to look at reviews when they come, not for me to tell him to, he shouldn't buy on my word, or anyone else's word, especially when we're speculating based on what's there now.
Who is being hypocritical?
You seem to be arguing that the 2500K will be superior to the 5800K. This is probably correct. But if the 5800K can match stock 2500K performance after being overclocked then this is going to be a very good CPU for the price.
After all don't lots of people buy GPU's that are slightly down the range and overclock them to beat higher priced GPU's. Same thing with this.
You're missing the point entirely though.
If it turns out a 5800k OC'ed can match/best a stock i5, what about when the stock i5 isn't enough anymore? You'll need to upgrade, the stock i5 can clock 40%, ergo lasting longer, thus better value.
