I noticed there were numerous topics on which PC would be best for FSX. I am also upgrading my system on a tight budget. Can anyone advise me on which is the better choice between these systems. Intel Core i5-2400 3.1GHz 64 bit Quad-Core Processor 4GB DDR3 1333 ATI Radeon HD 5450 1GB Phenom II X6 1055T(2.8GHz)4GB DDR31TB HDD CapacityAMD Radeon HD 6570 (1 GB) Intel Core I7-870 2.93GHz Processor8GB DDR3 MemoryATI Radeon HD5750 Graphics Card

When you are upgrading (it all depends on the motherboard then)You might want to read this

"this" needs to be updated... the requirements that are listed are unlikelyto lead to a satisfactory result - and why two monitors?

Considering you are upgrading and haven't mentioned the mobo, you are gonna need to add that to your list. I would go with the i5 2400 build but a better GPU, you are gonna bottleneck badly with that thing. Probably go for a GT 430 for your budget but really at least a GTS 450.

Actually I would go with a 2500k over a 2400 or a better GPU. CPU is the primary component for FSX. Shear clock speed is what it feeds on. Going with a rather lacking and minimal overclockable CPU (the 2400) but a better GPU is not going to impress you in the end... Btw off topic here, please correct me if I am wrong. I thought posting links to the same external blog repeatedly was against forum rules? Isn't this counted as advertising?

I don't think so, people have links in their sigs and as long as "Virtual FSX" isn't selling anything commercially then I think it's ok to post the link.

I had a flick through Avsim's terms of use. It says that you can't advertise a site that members can sigh up to and could potentially compete with avsim. I'm not sure if thats in that category

I am a member of lots of fora and have linked to them when addressing something where I thought it more helpful to post a link, I personally do not see that as advertising. Perhaps I should have a read of the T&C's, wouldn't want to get into any trouble here at AVSIM.
