1080p gaming rig no need so high budget.
to use up ur whole budget, this is what i would go for myself (no storage as u mentioned):
| i5 12600kf + msi pro b660m-a wifi ddr4 | 615 (600 + 15 for non full system) | dynacore | fast 10-core cpu, good quality mobo |
| id cooling se 226 xt | 52 | shopee | recommended by users here, comes with native lga1200 support |
| team group t create 2x 8gb ddr4 3200mhz | 71 | amazon sg | absolute steal for decently fast ddr4 |
| powercolor rx 6800 red dragon | 610 | amazon sg | best priced high end gpu right now |
| super flower legion gx pro 650w | 98 | shopee | good value quality psu |
| corsair 4000d | 109 | shopee | spacious premium case |
total: abt 1550, can even do 4k gaming.
u probably dont need such a high end system though, a mid tier build should be enough. plus, u spend so much now on parts that are going to be superseded quite soon. so i would recommend the following build from dynacore, plus u get local warranty for all the parts here:
| i5 12400f + msi pro b660m-a wifi ddr4 | 467 | still reasonably powerful 6 core cpu |
| klevv bolt x 2x 8gb 3600mhz | 85 | cheapest fast ram |
| powercolor rx 6600 fighter | 440 | best value current gen gpu, will even do 1440p gaming well |
| super flower legion gx pro 650w | 105 | same as above |
| corsair 4000d | 122 | same as above |
total: 1220. honestly even a 1660 super will do just fine for 1080p, but brand new they are way overpriced, sometimes costing even more than the 6600.
