Is this a good buy today?
Market confidence: MediumAt CAD 2640 the RTX 4090 is priced in line with its CAD 2700 representative market level. Only one retailer currently backs that price, so the level is a single data point rather than a market.
Limited market: only one retailer currently has a verified offer, so treat this price as a single data point.

Where it stands in the field
Two different questions, side by side. Performance compares what the hardware can do; Value compares what that capability costs at today’s price. A product can rank high on one and low on the other — that gap is the point.

Balanced has no letter: it is a weighting preset, not a capability rubric. A grade answers “how well does this handle that job?” — price is never part of it. Relative Value puts the current market price back in.

- You want strong value for Light Use specificallycompeting products deliver so much more for Light Use per dollar that no price this model realistically trades at reaches the strong-value mark for this job

Judge the change in the active scenario, then make the cash gap explicit.
Using page scenarioWhat are you upgrading from? These are the axes we compare on, and where this product stands in the current market.
We rank upgrades by out-of-pocket cost — the new price minus what yours is worth — not by sticker price.
Only candidates that clear the configured meaningful-upgrade gate will be shown; roles are omitted rather than filled.
Capability differences are expressed as tiers and index points, not as benchmark percentages we did not measure.

Whole-system figure from the board vendor — it already allows for the processor and transient spikes.
1x 16-pin required
Adapters work but add connector bulk and need extra cable-bend clearance.

Front radiators and fans eat into the figure a case advertises.

FAQ
Do all RTX 4090 boards have the same physical design?
No. Dimensions, slot thickness, cooling, power connectors and display outputs belong to the exact board. Use the Exact version selector before checking case or PSU fit.
How much case clearance should I allow for the RTX 4090?
Tracked boards range from 358 to 358 mm in length. Select the exact board, then also allow for front radiators or fans, card height, slot thickness and power-cable bend; length alone does not guarantee fit.
Why does Relative Value change when I choose another scenario?
Each scenario changes the weights applied to capability, price and the other published factors. The hardware facts stay fixed, but the value question changes, so its score and rank can change too.
