Some quick questions

[HankScorpio]

Hello I'm very nearly buying a new GPU

I'm thinking of getting this

What does the B-grade mean?

Is this better than getting a second hand 5870 @ £100 ?

I'm currently using a 5770 so would switching to nvidia drivers be easy?

Thanks

B grade means that it could be a slight imperfection like a scratch on the case or damaged packageing or something similar making it a "second" and unable to sell at full price.

Switching from ati to nvidia is easy as long as you remove all the drivers properly.

At to weather the 460 is good value at £150 im unsure.

gtx460 is a cracking card. However for 150. you could get 2 for that price

His link is for a 470. Personally id get a 6950 for 200

personally, i'd wait for next gen. othrwise, a 6950 would probs be the best choice

the first batch of 7 series won't be a massive jump. They always release the low end first.

hopefully the 79XX won't be too far after that

Could I xfire my 5770 on my 500w PSU?

I've just used extreme PSU calculator and it says I'm using 355w and another 5770 would use an extra 100w ? and i'd be at 455 with a little bit of head room?

on the calculator it comes out at 415w with crossfire.

if it's a decent brand PSU, then yes

Akasa PaxPower 500W Ultra Quiet Power Supply

Bought it from OcUK one year ago for £60, never had a problem with it.

I guess it will be okay

Okay well I'm gonna give it a shot and have just ordered a mint conditon sapphire 5770 from ebay to go alongside my MSI hawk 5770.

My question is do both crossfire cards need to be at the same core clock/memory frequency?

Currently got my hawk @ 975/1250 and think the sapphire can do 950/1250. Would that be ok, or do I need to bring my hawk down to the same as the sapphire?

You can run the cards at different speeds though I imagine the closer you can get them the better the overall performance.
