Hi, I am getting sick of endless freezes caused by the Asus Striker II NSE.I decided to get rid of this crap.Two options are considered:1. MoBo only replace - Gigabyte EP45 series (1333MHz DDR3 support)2. go for i7 /i5 - I cannot allow more than 6GiB 1666MHz and 870 (4x2.93) or 930 (4x2.8) CPU. Eventually i5-670. It has two cores, but faster than other i7 quads.Would I benefit from i7/i5 technology? It will be used only for FSX - CPU dependent app.Socket 775 is much outdated technology, but I do have QX9770 for it (3200GHz) and good OCZ DDR3.Video card used is GTX280, I would stay with it.Any advise or links will be much appreciated.PS I found a i7 960 D0 3.20GHz with 3monts warranty but very good price (approx. 350USD)

As an owner of three Gigabyte EP45 UD3L boards, I whole-heartedly recommend them. However, if you feel like you need more performance, a new motherboard isn't going to give you that. If that's the case, then go for an i7 system. Oh, and if you do, let me know if you want to sell your QX9770, I wouldn't mind upgrading one of my dual core systems to a quad.

Good idea, then. I had similar issue with an MSI-board that didn

Yes, moving from Core 2 to i7 will give you increased performance. Many i7 users that have made the transition from Core 2 Quad to i7 have stated it was a tremendous difference for MSFS, but perhaps not as much for other programs.
