RAM - go for 8GB (around 3.5k ata ang 2x4GB)
then yung natira pwede higher video card (depends on what you do with the PC)
SSDs are good para mabilis ang boot but its not really that critical (and baka hassle pa since you have to migrate your files and OS to the SSD)
BUT if your OS is 32 bit, then there is no point in getting 8GB RAM, your system can only use 4GB. in that case, dedicate all that 10K into video card, maybe a GTX960 or R9 280 (brand new), or sell your GT740 and maybe have enough for maybe R9 280x, or even GTX970
