UEFI only format install?

I decided to format my PC today which I have a z77x-UD3h Motherboard. I went into my Bios and I loaded up default settings restarted and loaded the bios back up. I inserted the windows 7 DVD but went straight into the bios and changed Bios features to run only in UEFI including the Other PCI Device Rom Priority. I also changed the boot up option on the disc to install as UEFI. I noticed be for that these option I changed had mixed Legacy and UEFI which I think Boot mode was in UEFI and Legacy but as said changed that to just UEFI only. After Formatting and reinstalling and noticed in games that they where much smoother including the internet load times. Would installing just in UEFI make a difference or is it just wish full thinking lol.

Been trying lots of ways to get the graphic card HDMI to work but as some said on here it be most likely a faulty HDMI socket or something. But formatting in Uefi only does seem to have improved loads.

Thanks for any input.

There's no performance difference between using MBR or UEFI for the partition table. The file system Windows uses is still NTFS in either case. Unless there's something unusual about your motherboard which causes it not to perform properly in MBR mode.

I personally avoid UEFI when possible because it is not compatible with a number of different utilities.

I didn't no Uefi wasn't compatible with certain Utilities. But yeah I checked the in the computer Management and its still NTSF. I will try this for a week and then go all Legacy only for week and see the difference. Like you said it might just not like the other way. But loading websites is much faster as be for there where several 2nds be for the site loaded and now its almost instant.

It's probably more to do with the fact that you've formatted, you probably had some software or configuration issue on your last installation causing a slowdown.

Yes unfortunately GPT partition tables using the UEFI are not compatible with a number of popular boot utilities like Truecrypt, and some operating systems do not support it either which makes it unusable for dual booting some linux distributions.

Hi. Well it defiantly had something to do with legacy install as today I tried installing Legacy only and straight away I notice a slow down. Computer took longer to load and websites also took longer to load up and was on the white page loading screen for around 4 2nds. I no I said I would give it a week but had nothing better to do on this warm and windy day so tried it today. I didn't even try a game as with the computer it self and the internet where much slower I thought I would leave it and save time. I have even tried installing it by default bios setup which has both legacy and UEFI and that also is slow. Seems strange but im not complaining hehe.
