Xeon CPUs (they are not chipsets as what you mention above) are designed for servers, so they do not have a GPU, and have hyperthreading to run more parallel jobs, and more L3 cache to support those additional processes. Servers normally handle a lot of "processing jobs" in parallel, with multiple different clients requesting from the CPU at the same time, so the higher capability to support each job request along with the memory will make the
Xeon CPU perform better in those environments.
If there are only a few threads running at the same time, like for example in computer games of today, then a faster clocked processor will finish that same job faster.
So in short, whether a Xeon or a OC i5 is faster depends on the software or program that you are using. Generally, for workstation type software (image editing, video editing, etc) that can run many jobs in parallel, or if you are running multiple programs at the same time,
then Xeon will be better. If you are playing a FPS game, then an OC i5-4670K would be better.
However, for gaming, normally the bottleneck is the GPU, so in your specific example above, the GPU will most likely be the bottleneck at 1920x1080 high quality resolutions before the CPU is the bottleneck, so it is possible there will not be much of a difference when gaming between the two CPUs.
I am not familiar with Asrock motherboards, I am most familiar with Asus, and next I use Gigabyte, so I cannot really provide an opinion to you on that one.
You can buy the parts in Low Yat Plaza ... one of the best places to get computer hardware. I buy from one shop in Low Yat because I have been buying there since Low Yat Plaza started about 15 years ago, and I get very good service from the owner, and he is like a friend to me now. Any of the main shops are OK, I think.
For movie-watching, look for brands that use IPS screens, like LG, and Dell. IPS screens give good color reproduction, and although contrast is not that good, monitors from Dell give good contrast from IPS screens. I am using Dell monitors now, after going through a few brands.
Wireless adaptor is pretty standard, I normally use TP-Link for their good replacement policy, and never had an issue.
KB+Mouse I use Logitech, but I also think these are pretty standard, and any brand will do ... the more important is whether you feel comfortable with the KB/mouse or not.
Thanks for taking your time.
So basically I guess I will go for the Xeon CPU for the reasons.
What is the shop in LYP? The price alfiejr quote is the generally lowest among others but he doesn't mention the place.
Yeah I guess will go with Dell U series too.
Thanks again.
