Hey everyone!I have recently decided to go with a single GTX580 for FSX.How much of a jump in a performance will I see going from an i7 920@4GHZ + GTS450 ------> i7 [email protected] + GTX580Will the GPU make a difference at all?

Heck of an uppgrade in graphics you should be well happy with that , Be careful when overclocking the i7 2600K , its quite difficult to get past 5.0Ghz without going to 1.5 Vcore , and dont want to damage the processor , but you will have one heck of a system there, congratulations on it hunny !! xxx

are you kiddin you will getsuperb performance from that 589 gtx and processor.

sorry about typo evga 580 gtx 1.5 gb

are you kiddin you will getsuperb performance from that 589 gtx and processor.

but the question is not regarding absolutes. it is about relativity to the other system.
