Hi Guys,

I am starting this thread so i can get some potentially helpful information regarding a new computer i want to buy. I want to get a custom built but i don't know how to build one my self. I have a budget of around $3000 (AUD) and i plan on using my PC for a variety of things like gaming and programming, i already have an idea on the GPU and CPU i want and they are the i7 920, and also the ATI Radeon 5790 but unfortunately i don't think thins GPU will fit into my budget.

If anyone has some good advice for what to look out for and or any recommendations please reply and i would prefer text rather than links but i guess inks are okay too.

Thanks guys.

A concise expert note for that ties together the thread: the real compatibility problems with an LGA1366/Core i7 build paired to a top-end dual‑GPU card are socket/chipset and memory layout, PCIe slot spacing, PSU capacity and connector type, and physical card clearance plus cooling. was right to flag the 5970 as a different class of card, and ’s idea of using a custom‑build shop makes sense — bring a short parts checklist so the builder matches parts correctly. (techpowerup.com)

Motherboard and CPU notes: the Core i7‑920 fits LGA1366/X58 platforms; X58 boards expose triple‑channel DDR3, so memory should be bought in matched 3‑stick kits and populated per the board manual. Pick an X58 board with a robust VRM if overclocking, with enough full‑length PCIe x16 spacing for large cards, and confirm the board’s CPU support list / BIOS revision before purchase. (techpowerup.com)

GPU, power and case guidance: the Radeon HD 5970 is a long, dual‑slot, dual‑GPU card (roughly 311 mm), has a high board TDP (~294 W) and requires external PCIe power (6‑pin + 8‑pin). AMD’s launch guidance listed ~650 W minimum, but real‑world rigs with a Bloomfield i7 and any overclocking commonly use 750 W–1,100 W quality PSUs for safe headroom. Choose a reputable, high‑quality PSU with the right connectors and plenty of +12 V capacity, and verify the case has the clearance and airflow for a 2‑slot, full‑length card. (techpowerup.com)

Quick checklist to bring to a builder or use when ordering parts:

  • CPU: Intel Core i7‑920 (LGA1366).
  • Motherboard: X58 chipset, confirm socket and BIOS/CPU support.
  • RAM: matched triple‑channel kit (3 sticks).
  • PSU: quality unit, min ~650 W but 750–850 W recommended, with 6+8 pin PCIe connectors.
  • Case: full tower with >= ~320 mm GPU clearance and good airflow.
  • Cooler: aftermarket CPU cooler if overclocking; request an out‑of‑box POST/test and warranty paperwork.

If budget or heat is a concern, consider a single high‑end GPU option instead of a dual‑GPU board to save power, space and noise.

5970 I think you mean :). Should be able to squeeze it in with a $3000 budget :).

Oh really thats kind of a relief but i still have other questions, are there special types of mother boards or processors that i will need to have so everything works together please reply its really important.

Thanks for the help though :) :)

I'd recommend going to a shop that custom builds computers and you can explain what you want and they can match the computer components to you needs. They will also give you good service (generally) -- at least much more than Dell, Gateway, etc.
