hi anyone can help suggest? thanks
in addition, anything i should buy from IT show this week?
Your budget very workable....depending on the games you play.
Monitor will eat a chunk of your budget. If your 'Peripherals' include a $150+ mechanical keyboard and a $50+ mice, then you have a lot lesser to work with.
Try to narrow down on what mouse/kb/monitor you want. Especially for peripherals, because it usually comes down to personal preference than asking someone to pick for you. Can be $15 KB+Mouse combo, can also be $350 HappyHacking KB + $200 Mouse.
Simple i5 + 8/16gb ram + 200mb ssd should come up around $700-900+ for the entire PC excluding GPU depending on the luxuries you spend (Casing, more storage, OS, more RAM, better cpu, better mobo).
Then the rest just splurge on GPU. Your budget can def fit GTX970 or 390X. If you playing latest AAA games and expect to run 120+fps at max settings though, consider upping budget for 980TI/FURY X or wait for next gen GPU coming out late Apr/May.
